Title: Yamaha TW200.. the swamp donkey
Post by: Hurco550 on Apr 25, 2018, 23:06:09
I've long wanted to own a Yamaha tw200, but every time I've found one for sale, people tend to be pretty proud of them and ask what is in my opinion a little bit too much money for a long production run small CC bike. That is until yesterday when my "harmless"  daily Facebook Marketplace search turned into a spur of the moment 4 Hour round trip after work to go pick this gem up. It's a 1988 model that has been robbed of a few parts by the previous owner to keep another tw200 on the road. Since it's incomplete, I don't feel too horrible about some minor customization to turn it into a neat and quirky little trail bike.

As far as the title goes, it's the same old story. It was in his grandpas name, grandpa died and he cant find the title. I did have him fill out a bill of sale, so I can go the vt route, but at the moment it may get a spare tag thrown on to bop from trail to the next.

The plan for the bike is to make it a fun, cheap little ride to take with me Down to Georgia When I visit the in-laws which is usually about 6 times a year. My dr650 is a blast, but after riding Mr. E's meatwad xr200, I realized how much fun a small CC lightweight beater bike can be. I've seen pictures on and off for a few years of this red tw200 around and have always thought it has a neat look with a vintage tank and stripped down Style. At the bones it is kind of my inspiration for this build with the exception of a few things added that will make it more rideable off road including fenders and the stock airbox.

I have also kicked around the idea of running another rear wheel out front. There are a few good forum posts online, and it's a fairly straightforward project which uses BW 200 Forks and triples.

One of the things that has always drawn me to these little bikes is the unique and almost comically disproportionate balloon rear tire. Replacement tire options are a little bit few and far between, but there are actually a few larger ATV tires that fit and are also d o t rated

Progress may be slow but I will try and keep the thread updated as I go

After seeing how much fun Ephraim has on meatwad, I decided that a lightweight may be more fun than constantly man handling that dr650 off-road (even though it does the job well). There is just something about a cheap, simple beater bike that is appealing to me. Bare bones, no fluff, kinda like taking the original cafe racer ideals and transferring them to a small off-road machine.

Ive been slacking a bit on updates, but I have still been tinkering around on this thing. I pulled the motor out and finally got the side cases (that a previous owner had graciously decided to use jb weld as "gasket material") pulled off, beit with a good amount of grunts, bloody knuckles and ez outs since ever single phillips head had been rounded off. What I found when I drained the oil was a highly undesirable paste of goo and metal shaving, along with a little more goo, and just when I thought I had found it all, more metal shavings.

Now, after a little bit of google-fu and some forum reading, ive found that these little tw lumps are notorious for shedding metal shavings, and there is a hippy esqe attitude in "the tw200 groups" of shavings are fine, just run it, but even so, there seemed to me an obnoxious amount of them. I figured no time like the present to dig in and see where they are coming from. I wasn't planning on splitting the cases, but I guess plans change. Upon removing the inspection cover for the cam chain, I had a "well theres your problem" moment. The engine was pretty obviously starved of oil at some point and the aluminum cam bushing had been eaten away.

To remedy this I will need source a roller bearing and a new cam. Its been done before and documented, so hopefully wont be to big of a deal.

Also, here is the expected pic of parts piling up for the build ;)

Not sure I'm ready to give up yet. Entire engine swaps are pretty tricky due to the extreme offset on the countershaft sprocket. There is actually an outer carrier bearing that is part of the sprocket cover. Even a bw350 motor utilized a jack shaft on the swinger, so its not a real easy swap at that. Heads, however are a little easier to come by. I don't have the list handy, but a number of tt225 xt225 xt200 and a few others are direct swaps, and can be had complete with cams, valves and rockers for around $70 used.

That said, if I find a complete better tw200 for a reasonable price, this one will quickly become a parts mule.

 So after some more digging through the motor, I just found way to many shavings and other unsavory chucks of metal. I decided to jettison the stock lump in favor of a predator 212cc with a torque a verter clone, and just end up with a big ol fat tire mini bike/ pit bike.

Here's the engine sitting roughly where it'll go.

During my mid Ohio swap meet adventures, Mr.E made a stupid impulse decision and bought a $10 steel Honda atc tank. Worked out well for me, because between that and the $5 Yamaha dirtbike seat, this thing will be sitting pretty.

The rear subframe has a weird drop seat  Style Bend in it which did not work well with the flat bottom vintage dirt bike seat, so after a couple hours of cutting and de tabbing the frame along with bending up some 1/8" wall 3/4" inch OD tubing, I have a subframe that fits much better. I left the frame a little long until I decide what I am doing to mount a fender and possibly a luggage rack. There will be more bracing added, but the basic shape is there.

Ran out of mig wire while trying to finish up the sub frame, so I decided that I'd wire wheel the paint off of the tank. That is where I found this tasty morsel. Looks like I'll get plenty of practice pulling dents I guess lol(https://uploads.tapatalk-cdn.com/20180712/372dc06b507b0718c6008a7c1ec9670d.jpg)(https://uploads.tapatalk-cdn.com/20180712/b67556f2683f3fd4e77002865738daec.jpg)

Got the sub frame and seat mounts pretty well wrapped up, and made up a mount to use my old dr650 front fender out back. It actually fits surprisingly well, even if it looks stupid with the seat off. I will likely make up some aluminum side covers as well which will cover up the lower part of the fender.

The more I look at it, I'm kinda kicking around the idea of trying to find another tw200 lump to stick back in it. The predator would work, but really looks goofy. We shall see.

I was kinda hoping for this, or maybe an XR/XL motor or something.  I know there is the CS issue with the fat tires, but I figure machining up an offset to weld to a sprocket or something might work just as well.

I had made up some quick alloy spacers for the front tank mounts just to get it in place, but wanted to use rubber ones for the finished design. Surprisingly, no-one makes off the shelf mounts to adapt an atc tank to a tw200 ;)

I found these "boat plugs" at the local Menards, and the o.d. and length of the rubber part turned out to be exactly right (score), just had to drill out the middle a bit, and Walla.

Also turned and welded in a threaded 10mm bung to mount the back, using rubber/ fabric washers top and bottom.

I spent the other part of the day going backwards on the project. When I was planning on putting in the predator engine, I cut a chunk of the down tube out to clear. Now that I'm putting a stock motor back in, I had to put it back. Glad my buddy hadn't hauled off scrap yet haha

I turned a slug on the lathe that fits the i.d. of the frame tube, then cut a ridge in it, which I used to line up the tube via the weld seam in the tube. Welded er up, ground er a bit and she's good as new.

Missed the FedEx man with my engine this morning, so it'll likely be in tomorrow.

Here's a few pics of where I'm planning to go next.

One of the neat/ quirky things that has always drawn me too the tw's is the balloon rear tire which in stock form is mounted on a 14" x 4.5" rim. Tire options are a bit limited unless you go with an atv tire, which is what I planned to do. The kicker is that there are multiple cases of people either having to trim the beads or use upwards of 100psi to seat the beads on the tw rim, of which there are several reports of damage to the tire and injury.

The next "common" thing to do is to mount a 12" or 14" trailer rim to the rear hub, which is the route I plan to use. Those who have done it, tend to use the stock hub and weld a flange onto it. I am planning on making a hub from scratch, and at the same time, mount up a disk brake, caliper and hanger from a dr350.

The front wheel will likely get the same treatment, but with custom triple trees to widen everything out, as well as a set of xt350 forks and a disk brake.

These wheels are on the way and these are the tires im eyeing.

The red and white bike are what the bike will likely sit similar to, less the spoked wheels.

Man, I hope the same thing doesn't happen to your motor that happened to mine when I wasn't there to receive it the first attempt.  I swear they trashed the motor having to take it back and re-deliver it. 

Also, have they tried the ratchet strap method to getting the tires on?  That's how I do all of my big tubeless tires like tractor tires and the trike tires.

I am really hoping that it doesn't get destroyed too. At least it's insured but still it's a pain. That could be the case because I'm pretty sure it's like 80 lb.

I think they have used all manner of methods and Lubes and standing on your head with your eye cross crooked to try and get tires mounted. The take away from it is if you get a flat on the trail you are pretty much screwed on a change as the beads are really on there and terrible to get off.

 plus, they still run a tube when they put it on the stock tw rim. I don't think it's a sealing issue, it's more that the bead is to tight.

The beads on the Van Van tires were insanely hard to get off, even with the two piece wheels. I had to bring them to a tire shop and even they had a tough time getting 'em off.

The ATV tires I'm running are beastly though. Apparently you can run a TW rear tire on the stock Van Van front wheel, too.

Motor came in seemingly un-harmed from Texas today. This one "supposedly" ran with 1800 miles on the ticker. Seller thinks it needs a stator as it would run until it got hot and then quit, but run again after it cooled off. To me it sounds like it could be an ignition coil too. Either way, everything looks in order, including red rtv on a case cover gasket. Ill likely just mount it up without digging to far into it. If a problem presents itself ill fix it, but less a valve adjust and oil change, I'll likely leave it alone until I am given a reason otherwise.

 Got the engine stuck back in for some more mockup work, and have to sort the wiring.

 I decided that since I still want this to be a capable off-road machine, the stock airbox is probably the best way to go since it brings the water chug level up higher over the pod filter option, and it acts as an inner fender as well. I have some fab work to do though, as I build a new subframe and the mounts went bye bye with the old one, and my new rear mud flap mount is in the way, so I'll have to sort something different there as well. The stock box is ugly, so some vintage style side covers will be made to cover it. (https://uploads.tapatalk-cdn.com/20180729/969df984611822bdbd741168b7a7b90c.jpg)

Also, I decided to order this tire instead of the ones posted earlier. It doesn't look as "cool" as the mud tires, but I'm liking the rounded profile and knobbies on the sidewall. May help keep it from washing on a corner better. Either way, an atv tire will be a trade off performance wise on a bike, but while it may not corner on an mx track as well as the stocker (as if I'm worried about that on a 17 h.p. dual sport) it should help it tractor through mud, snow and single track better. 

Still undecided on what tire ill run out front, and it may possibly stay in stock form out front until after I get this thing moving under its own power. (https://uploads.tapatalk-cdn.com/20180729/a499631a955204063b442a7af00214c7.jpg)

Iron Pony had these on close out for $40. It's kind of a hard compound MX Tire but it will get me by until I figure out what I'm doing with the Fat Tire front end conversion. Should be plenty meaty. Going to drop it off at the tire place tomorrow to have the stock tire pulled so that I can bring the wheel back home to true it up and drill it for a rim lock, then back to the shop to have it mounted. On a stock tw200 with the "hugger" type front fender it wouldn't fit, but I'm making a bracket to do a high fender mount so it shouldn't be an issue.

Started working on the rear wheel mod. Cut the center out of the trailer wheel, ill post up more detailed pictures of what im doing with that later on.

Couldn't help but to mount up the tire up. It spooned on easy enough, but took a little boom juice to seat it. Its a little less than 2" taller than the stock. May play around with a beadlock too, depending on whether or not it tries to spin the rim at low psi.(https://uploads.tapatalk-cdn.com/20180802/fed5ca32f65df297b645897005aaeb64.jpg)(https://uploads.tapatalk-cdn.com/20180802/6db24593ed6e9b0a893b55c8bb36401e.jpg)(https://uploads.tapatalk-cdn.com/20180802/69a46f3fa6573e7d42a5759ce4073910.jpg)(https://uploads.tapatalk-cdn.com/20180802/1e9dac40fbb0f562910354f5897ce2d5.jpg)

Got a little time to tinker around in the shop today. I trued up the front wheel. I think there were only about 5 spokes that weren't lose. None of the nipples were seized up at least. Also drilled for a rim lock. Getting the tire mounted up tomorrow.

Also, went ahead and put in New tapered neck bearings, as the balls in the bottom were completely missing. Threw on a set of atv bend high bars that I grabbed for $5 at mid Ohio. They were destined for my dr650, but they will do the trick on the tw for now. A bird in the hand and what not.

I picked up this fender off of eBay for $15 shipped. It was listed as a "universal vintage dirtbike fender" but the gurus of the vintage dirt world said its a Yamaha xt deal. It is the right era for the look I'm going for on the bike, and I dig the big louvers in the back. It's just safety wired on right now, but I'll eventually make a bracket to mount it up top.

I had racked my brain on the best possible way to mount the trailer wheel to a rear spindle, and what I had planned to do was make a complete spindle from scratch, and use a bw200 wheel mount center welded to it. I figured that if it can hold up to braking and steering forces on the front of a bike, it should be able to hold up to braking and driven forces out back, at least on a 17 h.p. bike. I bought a used bw200 front hub on eBay, and it just came in. I was pleasantly surprised to find that it should work as a compete unit with a little bit of modification. The rear drum from the TW bolts directly up to the flange on the bw hub, and with an extension tube  to mount a sprocket carrier and a bearing internally, it'll bolt right up. Next I need to make up a set of tabs that'll weld to the wheel and bolt up to the hub. Sometimes even a blind squirrel finds a nut.

I was even thinking about running a stock bw200 front wheel out back. It would be nice having an aluminum rim, but the only thing is they (as well as the atc rims) are 11" diameter vs the 12" diameter trailer wheel. I don't much care that the rim would be smaller, BUT the outside diameter tires available for 11" rims are smaller than what you can get for 12" rims.

Got a little lathe time in making the extension for the bw200 front -hub-to-rear-hub conversion. I had to turn a bit of the drum side tube of the bw hub down to make clearance for the brake plate to rest on the inner bearing race itself instead of the tube. I then turned and bored one end of a piece of heavy tube to press fit over the hub, then bored the other end to fit the bearings and seals. Yes that's right, bearings, plural. The stock tw hub had two bearings side by side on the sprocket side of the hub. I figured the engineers had a reason for this, so I'd do the same, plus it means that it'll use all standard tw200 bearings for if they ever need replaced again. I also turned a shoulder on the o.d. so ill have a square shoulder to press and weld the sprocket carrier against. I drilled a few holes to plug weld the extension onto the hub and pressed it on and welded it up. Once it was welded, I put fresh bearings in with the stock tw spacer. I checked for run- out, and all 4 tabs are within .020", and the welded tube itself is within .003". I'm not sure how close the tabs were from the factory, so I'm not gonna sweat it too much.

Also, a cool dude from the dr650 facebook page sent me a stock white fender for the cost of shipping, so it matches the white front fender.  (Stock rear wheel just mounted back on for some measurements)(https://uploads.tapatalk-cdn.com/20180816/16e49b9477ad33797309460d2bbf4e63.jpg)(https://uploads.tapatalk-cdn.com/20180816/ae1c05639d59073eb6010cd0a7622012.jpg)(https://uploads.tapatalk-cdn.com/20180816/a1b149bc023759a97fd0b68a8bc30d05.jpg)(https://uploads.tapatalk-cdn.com/20180816/a422f7c104d747515227e76a68f14eda.jpg)(https://uploads.tapatalk-cdn.com/20180816/69afd7cc072d5d21140641eb5b50ea40.jpg)(https://uploads.tapatalk-cdn.com/20180816/88a65c1cdf603b1dfb741ef92174053b.jpg)(https://uploads.tapatalk-cdn.com/20180816/1372499a378973cbbd5c4a28e1989221.jpg)(https://uploads.tapatalk-cdn.com/20180816/70c577b6ebdc4e49a68ede5bcc4f5381.jpg)(https://uploads.tapatalk-cdn.com/20180816/fac4a769edf5adc608e522aa6d65ff07.jpg)(https://uploads.tapatalk-cdn.com/20180816/60ed0cb13c4b2ccba1e312343da465c7.jpg)(https://uploads.tapatalk-cdn.com/20180816/6e0d95aaab38fcf5e894f572ed547191.jpg)(https://uploads.tapatalk-cdn.com/20180816/78d425629de40ff3bbf35dc3dc036fa7.jpg)

Oh I gotcha. Very well could be, but I've also spent a fair amount of time on a nearly 400lb. DR650 plodding through mud and various other gnarly single track, so I'm hoping I can handle a 240lb tw200, regardless of the front tire being marginally wider.

The bigger the tire, the bigger the contact patch, the more mud to move when you need to turn.

As was mentioned the bike is fairly light, and if he was able to manage his dr in the mud, the TW will be no sweat.

Well now that there's 4 pictures in a row of a fat dude mud running a dr650 on a tw200 thread, I digress lol

A fairly common carb swap for the tw200's is to use a Chinese mikuni clone carb for a bw200. The early tw200 carbs are known to be fiddly and prone to angst, so I figured for $18 shipped to my door, why not. There are a few fitment issues at the outlet of the carb, in that it is to long to seat into the ridge that's cast into the intake boot. Many that do the swap just run it with the carb not completely seated and hose clamp it tightly, but I figured why not just hacksaw and file it shorter so that it fits like it "should".  Even if it's just an $18 mikuni clone, it still feels weird taking a hacksaw to a brand new carb, but it fits a treat now. Ill likely have to turn an adapter to make it fit the stock airbox boot, but even that could likely be fudged a bit since I have to make new mounts for it anyways.

I'm thinking these could take a rear wheel (maybe on the front too) like I have on the back of my Tri-Rod.  Not saying you should do it to this one, but it sure does having me thinking about the future.
I was even thinking about running a stock bw200 front wheel out back. It would be nice having an aluminum rim, but the only thing is they (as well as the atc rims) are 11" diameter vs the 12" diameter trailer wheel. I don't much care that the rim would be smaller, BUT the outside diameter tires available for 11" rims are smaller than what you can get for 12" rims.

Sent from my SM-G920V using Tapatalk
So I may have to resend my previous statement about bw200 front wheels being 11-inch and thus taking them out of the running to use out back on the tw200. Through a little bit more research I found that they actually are 12 inch wheels which opens up many more Tire options in the desirable o.d. sizes , including the tire that I already have. It really may work out pretty awesome, since now I will have a lighter aluminum rim instead of a welded up trailer wheel. I made a deal with a guy on a bw200 Facebook page for this rim for $50 plus shipping. The bonus is that it will be a gold rim. Looks like I'll have to figure out how to paint the front one to match, because we all know that it would be irresponsible to not have gold wheels front and back when that is a possibility LOL the only thing that I am slightly concerned about is the fact that the bw rim is 6" wide as opposed to the stock tw rim at 4.5" wide, but it appears that there is plenty of clearance between the chain and tire to suit still.

Its a freshly rebuilt vintage super trapp. I was given explicit instructions that it goes back to him if I ever sell this little booger ;) you know me all to well deeds!

 The bw200 rim came in the mail today, and while I knew it was wider than stock, I hadn't envisioned how much wider in my head. (Stock is 4.5" wide and the bw200 is 6" wide). No big deal though, there seems to be plenty of clearance still. Wheel has a bit of a wobble/ shimmy that I may have to get creative about straightening out. The tire spooned on easy enough again and popped on the bead pretty easily as well. All in all I'm happy with it, and I'm glad that I now have a much lighter aluminum hoop than the steel trailer one that I was originally planning on using. Plus, gold wheel ftw.(https://uploads.tapatalk-cdn.com/20180901/bf413248c1c32254016dd3159fac23e5.jpg)(https://uploads.tapatalk-cdn.com/20180901/0c69ace914da08b9bb19468769c51ad5.jpg)(https://uploads.tapatalk-cdn.com/20180901/b3804e11991e5bc0e5e7c57ee4eec0aa.jpg)(https://uploads.tapatalk-cdn.com/20180901/3b108e8826452937032c0ee2cb6099fc.jpg)(https://uploads.tapatalk-cdn.com/20180901/e314653e0c6460302684d93c0143db89.jpg)(https://uploads.tapatalk-cdn.com/20180901/a22d18592f28b232e43138a4ed4c71f3.jpg)

I know this is a mongrel bike, but I couldn't help but to cash in on the gold rear rim and  paint the front to match. I gambled on a "metallic gold" rattle can, and it matched up pretty well. I used drinking straws slit down the length to mask the spokes and the old playing card trick to mask off the tire.

My wife and I are expecting our first child (due date is just a couple weeks away) and my better half seemed to think that "Getting the baby room ready" and "buying stuff for the baby" is more important than "Getting ANOTHER motorcycle running" and "buying MORE motorcycle parts" lol.  If we're being honest she is a freaking champ and I'm lucky to have her to keep me grounded.

I did however buy a feebay special chunk-o-stainless mandrel bent exhaust tubing to mate up the head pipe to the rad little supertrapp. Once I get that fabbed up with all manner of pie cuts and what not, the carb and air box mounted and a simplified wire harness, I should see if the ol girl will breathe fire again.

Progress on all projects will likely be slower (than the already snail pace) from now on, but I will get out to the garage and tinker away in the moments that I can.

Got a little more hackery done and mounted up the carb mounted up and made at last a temporary throttle cable for it. The bw200 clone carb came with a bent cable holder that didn't quite fit under the frame, so I swapped it out for a mikuni straight and short cable holder. The cable I had on hand also had the wrong style ball for the mikuni slide, so a little filling and hack style drill spinning with Emory paper and she is good to go. Once I figure up the wire harness and get spark, ill hopefully get this thing to fire. I feel like I'm at the point in this project that I have 90% of it done, and 90% left to go ha.

The more I I messed with it, the less I liked how the cheapo mini bike throttle felt. Both in function, and in that the cable came straight out the bottom of the throttle assembly. It seemed that it would be prone to getting snagged by tree branches in the woods and also, a failure of any kind out in the sticks could make for a long push back to base camp. I decided to try out a Yamaha blaster twist throttle conversion kit, since I know that the blaster used a mikuni as well. Feels like a quality piece of kit, BUT the exposed amount of cable at the carb/ slide end is to short, so I need to reduce the length of the sheath to expose more cable and put a new ferrule on it. Any advice on how to do so would be welcomed!

Maybe try a copper pipe cutter to get the length right, then you just need to snip it lengthwise to get it off the cable.
Title: Re: Yamaha TW200.. the swamp donkey
Post by: advCo on Oct 12, 2018, 09:21:12
You should be able to drill out the dimple(s) on the metal end of the cable jacket to get it off the cable. Figure out how much exposed cable you need (I usually pull all the excess cable to one end and measure that way).

Cut around the cable jacket with a dremel cut off wheel and be very careful not to nick the cable itself. You can actually cut about 85% of the way through the metal coil "inner jacket" and then pop off the coils with a screwdriver. I usually pry them open and pull them off the cable, then pop your cable end back on and  crimp it in place.

Thanks for the advice! Did exactly what you said, with one exception... I nicked the cable ugh.. ill keep an eye on it, but it'll likely eat at me and ill order a new one and try again. I also didn't care for the bind that the straight cable stay put in the cable, so I got an angled one, which should be much better.

Nice! As long as none of the strands broke you'll probably be ok. I try to cut about 80-90% of the way through and then break the rest of the metal jacket off so I don't hit the cable. Its a fine line.

I got a little time today to finish up the rear hub. I had a copy of the stock sprocket mounting bracket water jet cut and tig welded it to the extended bw200 hub. Then I chucked it up in the lathe to true it up and left a shoulder to keep the sprocket concentric. I replaced the original sprocket nuts and bolts with the pain in the butt bend over retainers with nylon locking flange nuts as well. Also, the cool looking ribbed bw200 front drum is the same dimensionally as the stock tw200 rear drum and literally bolts on. Once I get this the rest of the bike done, everything will get blown apart for paint, rear hub included.(https://uploads.tapatalk-cdn.com/20181020/768d3a870c7e42a9affa222ecd752e98.jpg)(https://uploads.tapatalk-cdn.com/20181020/d70acf8d76a143c74a751aaf5af69d61.jpg)(https://uploads.tapatalk-cdn.com/20181020/4c0594fc2f876b121ac9f9758f96aec8.jpg)(https://uploads.tapatalk-cdn.com/20181020/587233d18ae3f78eb4dd99edaae7b95f.jpg)(https://uploads.tapatalk-cdn.com/20181020/2cdd89d6b1bd24109155b1d063e342c1.jpg)(https://uploads.tapatalk-cdn.com/20181020/5d8c7bdf5d31b76d9e11cbfa87400bb0.jpg)(https://uploads.tapatalk-cdn.com/20181020/2726e53190e2612003143fd1813c360b.jpg)

I decided that it really does NEED a fat front tire too. Once I source a set of bw200 triples and do a bit of machining, I'll be there. I picked up another bw200 gold front wheel with a new shoe to boot. (https://uploads.tapatalk-cdn.com/20181110/f77396f2c3db0edf1d33e0f08272aaa2.jpg)

I found someone parting out a bw200 on facebook and made a deal on the forks. They'll need resealed, but the tubes are in great shape. The forks are a straight bolt on operation to the tw, even using the same bearings,  so not much magic to show there. The front tire looks shorter than it is probably due to the width, but in reality it is only an inch shorter than the stock tw200 front tire.

Well, I jettisoned the plan to finish the xr200 before putting the tw200 back on the lift. I spent a shameful amount of time this evening figuring out how to and implementing a way to use a tw200 front brake cable on a set of bw200 forks/ brakes. The tw cable is much cheaper and easier to find than the bw cable, plus in the happenstance that this fat front tire handles like do do, it'll make the swap back to the tw front end even easier.

I ended up turning an adapter up on the old south bend lathe, including some jakey y axis broaching for the slot. I'll have to go pick up some o.d. snap rings tomorrow too finish the job, but at least we're headed in the right direction.

Also, after trying to figure out the best option for a front fender, I bit the bullet and bought a decent used bw200 one. Should be here along with the tank on Monday.

The fenders are massive on the bw200, but the tires are 9 in wide and I imagine they would like to sling mud. The fender I had on there was 4in narrower than the tire and I don't think it would have worked very well. I may have to do something different with the rear fender depending on how much mud I get slung up my back LOL

Wondered the same myself. They have 1 negative feedback in the last year. The way they (or at least an employee) is acting, I'm about to do everything I can to make that number change to two. The latest reply said that ill just have to take it up with eBay. I intend to, fruitless as it may be.

I do love the little quirks of how the tw200 and bw200 stuff is made and is modular. The brake drums bolt onto the hubs which makes is super easy for a quick refresh on the south bend. I only took enough material off to smooth the grooves out, then a nice 80 grit cross hatch to help seat the new pads.

After staring at the rear hub a bit more, I decided that I wanted to beef it up a bit more than it is, being as it is really just a modified front wheel that now is doing the duty of a rear wheel. There were a couple weak points that glared at me as something that would possibly leave me stranded out in the middle of the woods.

I cut up 4 gussets out of 1" square tubing and welded them in. Safe to say its probably not going to flex or break now.

Haha, weight vs strength I got alot of "bang for my buck."

1" ◊ 1" x 1/8" wall square tubing weights 1.44 lb. per linear foot.

I used 14 linear inches of tubing for those gussets for a total of 1.68lbs. Add the weld wire and its still a sub 2 lb mod. I know that'd be alot on a race bike, but it's well worth the added strength on a trail machine imho. Ill just take a healthy dump before each ride and call it even.

I need to weigh the stock tw tear wheel against this assembly and see where its at comparably. I'm still thinking ill be lighter than original being as it's now a 12" aluminum wheel vs a 14" spoked steel wheel and I also no longer need a tube like the stock tw wheel.

I primed and painted the modified hub with rustoleum gold paint. It looks a bit gaudy by itself, but actually matches the wheel decently. Didn't get a weight comparison before bolting it back together because I didn't feel like taking both wheels into work to use the scale today. (We don't have a scale at home, I don't need that kind of negativity in my life lol)

I also (with wreckless disregard) painted the previously red bondo tank, covered it in stickers and put an even worse clear coat jon on it. It's gaudy on purpose. It's whole purpose is to get me through mid Ohio until I get the other patina tank fixed. I'll hopefully shake the thing down this summer and tear it down to paint and finish this winter.

Got a little time to work on the bike today. I'm t minus 30 days to have this stupid thing "cobbled together enough for hot laps at mid Ohio"

I finally figured out the reason I wasn't getting spark. After a bit of digging I realised that the pickup leads had been smashed and there were bare wires shorting out. I had chased my tail on this stupid thing only to find out that is was a stupid oversight on my part all along. Oh well, sure won't be my last.

Stopped by the local muffler shop and had them flare a piece of stainless exhaust pipe to build my mid pipe. Still need to finish tig welding it up, but should do the trick.


Also, now that I have spark, I put fuel to it, and she runs. Not gonna lie, hearing that thing fire up was what I needed to get the wind back in my sails.

FINALLY! 

You can probably remove the majority of the discs from the 3" Supertrapp.  Don't recall how many you got there.

Ive got 6 4" on the 400F and I think E runs 6 4" on his 400F also.

I need to find my chart.  But you might try 6,5 or 4 on the 200.

TBH I can't recall if its got any stuffing in it.  Just give it a light rap near the end (outside) w hammer and the baffle will work out.

Cassy and a couple buddies agreed that it matched, but part of me isn't sure that they arent just trolling haha

Its not a super nice paint job, but I wanted to cover up the bare metal. Electronics tray and inner fender plate up next. (https://uploads.tapatalk-cdn.com/20190608/37225e4aa26e7dc027c868f4a872bd6e.jpg)

I made up a quick little tray out of stainless steel to hold the cdi and limited wires that it takes to make the bike run. I also jettisoned the ignition switch for the use of a "hidden" toggle switch instead. (Y'all can't spill the beans to any would be thieves now that you know where it is). I still have the button up some loose ends but the wiring is done, at least until I have to figure out how to run lights.

Been pulling a few late (at least for me) nighters trying to button up some loose ends on this thing. I used teazers patented CAD (cardboard aided design) to make up an inner fender well out of .080" aluminum.  Traced it, cut it on the band saw and then rolled in a couple beads for a bit more rigidity. It should serve to keep the doo doo mud away from the rest of the bike well enough.

I also had to make up a #kustom exhaust guard, because I'm not going to pay stupid eBay money for the right one ;)

The atc tank doesn't have a petcock, as on the original bikes, the petcock was mounted directly to the carb. To remedy this, I put a ball valve in line as well as a fuel filter. For things that don't have to come apart often, I like using safety wire instead of those little devil clips. Yeah, y'all know which ones I'm talking about....

Also, I mounted up a number plate on each side, and one on the front as well, at least until I get the dual ruckus lights mounted and wired. Irk is going to print me up some numbers. There's a bit of method to this madness. I am contemplating running the old tw200 in a hare scramble event at mid Ohio this year, and to pass tech, you need number plates.

Today was the day, the tw200 made it around the yard under its own power. The carb needs some tweaking/ jetting, the fork seals still need replaced and the clutch won't disengage. The engine supposedly sat for some time before I got it and had some milky looking oil, so I'm guessing the plates are seized together. I have another clutch pack on order in case a few heat cycles don't break it loose.

Lenny likes it too, so there's that ;)

Looks great, Levi!  Kinna reminds me of the Rokon Trail Breaker I put lots of hours on when I was a teen.  You don't have the AWD, but it sure looks like it could.  Lenny looks happy, did you promise him that "someday this will be yours?" 

I've always wanted a rokon, and it's funny because I just mentioned to a couple buddies recently that this is likely the closest to a rokon ill ever be able to afford lol

Lenny already has a list of "his someday bikes".. gt250, xr200 and yes now someday this lol

Pretty awsome. I suspect others on the trails will either be trying to buy it from you or get you to build one for them.

The things are strange.  Lots of power through gearing and you'll run out of nerve long before it does, but at a max of 25mph (thought I'm not sure I'd want to go much faster on one of the things) they have a pretty specific use; hunters, people who work outdoors, etc.  Hovever for that use the four wheeler and the side by side have kind of rendered them obsolete.

Thanks man, I'm pretty excited to see how it handles the trails. Just based on hot laps around the yard I actually like this a bit better than the xr200, and it grips better too. I think the tw200 "feels" like it has a bit more power too, because it has all the traction and will not spin the back tire. All the power (the whooping 16hp of it) makes it to the ground.

A co worker of mine still keeps his in service for use during deer season. He swears that it is the best vehicle made for dragging a deer out of the woods. It will fit between alot of trees that an atv or sxs won't. If I ever find a deal on one, ill buy it.
