Title: 1973 DT250 Cafe/Brat build
Post by: Giancarlo124 on Oct 17, 2016, 20:18:40
Here is a little build thread on my dt3 build. Its going to be a cafe style build with a bratstyle seat. Ive already got a bit of work done to it and i have a thread on yamaha-enduros but i thought i would share it here as well.

So im just gonna start posting some pictures and keep you updated with my build.

So here is what the bike looked like before I did anything to it
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/IMAG0071_zpsignlrjru.jpg) (http://s1382.photobucket.com/user/Giancarlo124/media/IMAG0071_zpsignlrjru.jpg.html)

So pretty early on I shortened and detabbed the rear loop and bent up a seat pan for it(you will also see some crude rearset mounts but i ended up redoing those)
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/File%20Sep%2004%209%2025%2011%20PM_zpsfxs9i4dv.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/File%20Sep%2004%209%2025%2011%20PM_zpsfxs9i4dv.jpeg.html)

(http://i1382.photobucket.com/albums/ah248/Giancarlo124/File%20Sep%2004%209%2025%2054%20PM_zpsdhwjubhx.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/File%20Sep%2004%209%2025%2054%20PM_zpsdhwjubhx.jpeg.html)

Then I took the bike apart and detabbed the frame and welded on tabs for the rearset mounts
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/File%20Sep%2004%209%2020%2020%20PM_zpsuml6zaqg.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/File%20Sep%2004%209%2020%2020%20PM_zpsuml6zaqg.jpeg.html)

Next I cut out some new rearset brackets
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zpsvebtznsn.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zpsvebtznsn.jpeg.html)

(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zps0ocx7rfg.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zps0ocx7rfg.jpeg.html)

After that i put assembled some of the bike so i could do a little parts mockup and measure how much i needed to shorten the forks
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zpsmcoija8y.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zpsmcoija8y.jpeg.html)

After i shortened the forks
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zps2aqfwriq.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zps2aqfwriq.jpeg.html)

Fabbed up some headlight mounts and clip on handle bars
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zpsl5auf7wx.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zpsl5auf7wx.jpeg.html)

(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zpslopuwpi8.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zpslopuwpi8.jpeg.html)

And mounted the turn signals and made up a license plate mount
(http://i1382.photobucket.com/albums/ah248/Giancarlo124/Mobile%20Uploads/image_zpsqbq7qzha.jpeg) (http://s1382.photobucket.com/user/Giancarlo124/media/Mobile%20Uploads/image_zpsqbq7qzha.jpeg.html)

And thats just about where i am with the build right now, I should be taking the frame to get powdercoated soon. I will keep you posted.

Very cool.  I love the old Yamaha Enduros.  I had a DT1 for a while that had an RT3 engine in it... what a beast.

Good luck with the build!

Document the wiring on this one if you haven't done the wiring already.

Looking very cool,

Been a while but I got the frame powdercoated, put the motor back together and put it in the bike. Next I can start work on the wiring harness and making control cables.

Got some work done on the bike last night. I finished the shift linkage.
I had to drill out the shift lever and press in a sleeve to get a smaller diameter hole so i could use my M6 heim joints

Then I cut the threaded rod and gave it a little bend

Are you keeping the 21" front wheel or downsizing? Thoroughly recommend a fork brace when you get to that juncture. (Not that the front end will spend much time down on the Tarmac lol)

It originally had a 21 in the front but it has the optional factory 19'' wheel now. Do these flex a lot? Will a fork brace help?

Yep they will flex like spaghetti in every conceivable direction, however, even a steel mudguard will go a long way to mitigate it, and you have lugs available on the fork lowers to use. The more you can make the front suspension system work as a solid unit will pay dividends.
If one side moves up even a millimetre ahead of the other, by the time that is translated to the contact patch of a 19" tyre, you are looking at masses of misalignment and gyroscopic tomfoolery going on.
It's easy enough to weld one up comprising of two hoops, one in front and one behind and bolted to the fork lugs if you can't get a funky machined clamp.

Got some new parts today. Bars are from Hvccycle and fork brace is a vintage deal from ebay.

Nice Brace. I had one on my RT3 and it worked nice. I don't think I can run one on El Chivo because of the larger front tire now but I may just try.

Looking Great man,

Thanks man. loving your build as well. I think i will have to modify the mounting holes on the brace as it comes a little too close to the larger and lower headlight.

Been a while since I checked in here but I have gotten work done on the bike. I finished making new clutch, front brake, and throttle cables using the venhill cable kits that can be found on ebay. I also got most of the wiring harness finished, all I need to do is but some lights and wire them up. I put a new mikuni tm32 flatslide carb on. And I bent up a new kickstart lever cause the old one bent when the motor kicked back. Next week I will start modifying and fabricating an expansion chamber

Some of the wiring

pipe is an old one i found on ebay that i modified the header tube to go down, i kept the length right so it should be pretty decent (cant be worse than the stock pipe). No porting yet. has boyeson 603 power reeds in the cage, tm32 mik carb. And I have a GYT high compression head that will eventually go on. Glad you like it!

I made a metal (steel) seat pan and then had it upholstered. They wrapped the leather around the back and used some sort of contact cement to attach it

Those tires are the worst handling tires you can get. If you put a good set of avons, or shinkos or anything with proper rounded profile the bike would habdle 100x better.  Thise firestones with rectangular profike sides are for cars, not bikes that lean over in turns.

Yes- throw tires in garbage. Some idiot first did that and a few hole line of posers copied that wanker.

Makes sense. I mostly just liked the aesthetic of them but I don't expect them to last long on my bike tbh. So when they are gone I'll get a real set of tires

Their actually dangerous. Get a proper sized set of sticky performance tires and then ride the bike the way it ahould be ridden. Try it with those and you'll end up in the ditch.

An old Yamaha mechanic told me to be careful with sticky tires cause these frames flex a lot. Not sure if it's true or not

Post by: Maritime on May 13, 2017, 17:27:20
That is utter bullshit.  Traction will tell you the limits of the frame. Square profile tires will just stop gripping and dump you in a ditch before the limits of the frame are ever even close to showing themselves. You built a nice little 2 stroke fun machine put a goid set of tires on it and ride it.

Gorgeous!  Great job man.  Loving the headlight and the rear lights - are they combined blinkers/brake lights?

Have to agree on the tyres sadly.  Maybe you could invest in two sets of wheels?  One for show, one for performance.  I recently switched to an Avon Road Rider up front on my daily and love it - the confidence you get from good grip is amazing.  But above all, fun - way better lean angles etc.  See how it rides and handles first though of coarse!  Maybe it suits your style just fine  :D

Thank you! The rear lights are currently just two individual running and brake lights, eventually id like to figure out how to get turn signals in there.

Yea it seems like the Avons are the way to go, I definitely like the look of the firestones but as someone who also likes turning fast I can fully understand what you are saying. A second set of wheels sounds like a pretty good idea, wheels for this bike arent too expensive.

Just saw this thread and man I love it. You really turned that thing into an awesome looking machine. I am one of those that am really bummed that the firestones are such terrible tires, because honestly I think they look neat with the vintage look of the machine, but alas, they really are garbage (I know the dead horse has been beaten enough). I can though say first hand two thumbs up to avon roadriders. They grip beyond my ability as a rider. I think if you go that route after the firestones you will feel as though you have a whole different bike! (in a good way)

also, another dead horse that gets beaten a lot, watch that rear tire to seat clearance. I don't know your weight, but it looks a little close, and a good bump could make the seat contact it, "brake" the rear tire and cause a less than desirable effect aka "not keeping er' between the ditches"

Again great work. Not often someone pulls off the brat seat looking enduro-turned-café look like you have. Thanks for sharing it here

Thanks for the great feedback! It was certainly a struggle turning an enduro into a "brat-cafe". as for the tire clearance fortunately I am only about 105 lbs so the bike doesnt even sag when I sit on it, So fortunately I dont think the tire will ever hit the seat but I understand the concern

So I'm gonna do a little post build update here. Been riding the bike for a bit now, tuning as I go.

So I changed the header length of the pipe to get the powerband in a more desirable rpm range. Bike is getting closer to running really well. It pulls pretty good when it gets on the power band.

I also swapped out the Firestone tires for some Avon road riders. The Firestones look very cool but do not perform very well.

I also found that the shift drum detent was non existent so I replaced that as well. Mad the shifter feel so much better.

And lastly in addition to the r5 triple clamps I already had on the bike I went and got the r5 forks and installed the 2ls front wheel that I had on the shelf. Stopping performance is way better. If anyone is interested in putting this font end on their bike keep in mind that the r5 forks will probably be too short for Enduro riding. But based on the construction I'm almost certain you could bolt the r5 fork lowers onto the DT fork tubes

Little update, Just recently did some math and built a new pipe for the bike. Also installed a DT2MX top end. Bike absolutely rips now
