Title: MT250 Budget Build
Post by: JSJamboree on Jan 25, 2017, 11:51:51
Picked up a mostly complete MT250 about a year ago and its been sitting since.  With the RD mostly complete these days I think its finally time to get this thing road worthy.  Originally I wanted to do a CR top end swap but everything starting adding up to way to much money, so my plan is to try and keep it budget friendly.  From what I can tell at some point the motor blew a piston as its pretty knarley up top, but i drained royal purple out of the cases that looked to be in good shape so im hoping it was taken care of.  The carb was also in really good condition, almost looked new.  Already picked up a box of parts someone was getting rid of that has some pieces I needed.  This will likely become a commuter bike and i'll sell the VFR as Im ready to get the Vtec out of my life.

Goal is to have it road worthy by the first of May for the Kentucky Dakar.  Might be trying to call in a favor or two from MrE

Got the cases split to see what needed work inside. Piston exploded so it's been sitting a couple years with no piston, figured seals would be shot at the least. Inside it looks like the two small countershaft bearings need replaced and one of the crank bearings needs replaced. Crank itself seems to be in pretty decent shape, gross but minimal slop and the lower bearing seems nice. Transmission seemed to be about perfect.

Now time to go hunting for bearings.

I went through this with another bike, we never were able to find a bearing shop around the city.  I'll jump on a local forum and check again though, looking to save lots of $$$ for sure

Jordan is state side so shipping wouldn't be free for him. I just bought 2 6202SRS bearings from the local shop and they were 9.99 CAD each. that's after tax 8.61 USD. they would have been 3X that from a bike parts place. Using them to replace the cam bushings in the Virago so they don't size again.  PM me the details. I'll get you prices and I don't mind taking them to Merica to ship. I have to go pick up some stuff I ordered anyway.

Grabbed the crank bearing from the local shop, actually wasn't any cheeper than buying Honda online but I had already driven all the way to the shop so I did it anyways. Couldn't pass up the brand (immature and inappropriate comment I know). They couldn't even order in the countershaft bearing, super special secret Honda size so I'll have to nab that online.  Need to get the case all cleaned up this weekend anyways so it'll be next week before I look to start putting the bottom end back together. Gotta order seals too.

German bearing brand even though made in Korea, they are good quality, I have 2 of the same brand for the Virago. Used dozens in wheels over the last few years. I wasn't able to find the other one either any cheaper than the one you found at Partzilla, seems the only source is Honda.

Yeah, it was pinned back behind the stator coils bracket, there is also some damage on the coils themselves.  This motor has been apart before as there are some non OEM bearings already in it.  I'm guessing the last time they put it together the little bugger got picked up by the flywheel and they didn't realize it.  I'll have to check the transmission shaft to see if its there or not. That for sure was not the microfiche location I was expecting it to be on thats for sure

Nice.  Just saw this.  There's another MT in the family that has lost a bit of love.  Never thought an Elsinore, with all of the unobtanium in parts, could be a budget build.

My hope here is that the bike is mostly complete, I nabbed up a box of spare parts (which all need work) to fill in a couple gaps, and the rest i'll either figure something out or i'll go without.  I need to get out to the garage and see if that trans shaft bushing deal was extra or if its missing.  If its missing need to find a replacement for that so I can get the motor back together.  This got kinda back burnered since I picked up the KZ, but with the motor taking up my entire workbench i need to get back to it before I Start losing things.

Here is a pic, you can see that the motor is worse off than the last pic. Since then I've had the motor apart 2 more times fixing things. Found a few missing washers, etc.  worst off to this point is that I snapped a clutch basket bolt off using a 1/4" socket.  You told the gremlins about me, now I'm in trouble.

Well, got that bugger out and went to put it all together.  Once I did that the clutch outer and clutch center were tight together (wouldn't move independently).  Went to find out that the bearing wasn't installed far enough by the PO, so there were running without the washer behind the outer.  With that, the outer stuck out to far on the shaft.  So, I had to pull the motor apart for a 4th time so I could get the bearing in the right place.  Now that im back in there again, ive decided that the shift fork on the shift drum really should be replaced, though ive told myself its fine for now, keep the budget in the past.  So, I ordered one of those and now I have to wait for it to get here before I can put it all together again and hope this time its finally correct.

This bike has daemons, but so far they have all been driven by the PO.

Got the shift fork swapped over, the motor together, the clutch seems to be good now and it shifts through all the gears, only had to build it four times to get it right. On the bright side I feel pretty comfortable building dirt bike motors now, though they are a pain in the ass.

Next up, gotta get the frame cleaned up so I can get the motor in. Starting to find things I'm missing, some of which as the unobtanium previously mentioned.

Nice work so far. From afar it looks like a lot of the frame and suspension parts from the same year XL 250/350 should be interchangeable. There are quite a lot of parts available, so you may have some luck there.

Forks rebuilt, set the tubes in some metal rescue for 24 hours and cleaned them up. Still some pitting but nothing going through the seals.  Fresh seals, fresh dust covers, fresh oil.  Shitty thing that brought the party to a vault was I forgot to put a spacer below the new steering bearings on the lower triple. Tried to install it on the neck but it bottomed out.  The bearing didn't survive being driven off so now I gotta get another. One more week down the drain

Following along.

Hey electrical man, do you think you could spare me a couple of minutes to look at the wiring on this.  I would love to convert this from 6v -> 12v, however the stator is running three seperate circuits.

1) Runs the points to the coils (ac)
2) Runs the headlight, includes a resistor to kill extra power (ac)
3) Runs through a rectifier into the battery and powers the tail and turns (dc).

Ive been trying to find someone that has completed the conversion but only come up empty.  The best advice I got was to run 2 and 3 in a series, then possibly into a 6v -> 12v converter like you sell.  Im not sure it would work because the #2 stator wrap seems to ground out vs going to something so that might now allow it to work.  I dont know this stuff well enough.  Do you have any idea of how you would do that or if that idea would even work?

Here is what someone else said about it.  "From the diagram, it looks like you could unplug the white/yellow (headlight) and pink (rectifier AC in #2) stator wires and connect them together, then connect the other side of the white/yellow to the black-wire bus (DC positive) and ground the pink rectifier wire to the chassis (it's possible this wire would have to be run to the grounded end of the headlight coil, which would then be lifted from chassis ground). If the resulting voltage was very low, the yellow (rectifier AC in #1) and pink wires from the stator could be reversed."

Maybe with your setup, I would hook the W/Y to the P, hook the other end of the W/Y to black like they said for power the light.  Then swap out the rectifier with your setup and run

Y (converter) to Y (stator)
R (converter) to to R/W (harness)
B (converter) to ??
B (converter) to ??
P (harness) to ??
Title: Re: MT250 Budget Build
Post by: Sonreir on Apr 21, 2017, 15:55:45
We have a couple of options with this setup.

Like the XL and XR, this bike uses both AC and DC circuits. The white/yellow wire running to the front of the bike runs the headlight on AC power directly from the alternator. The ignition coil has a dedicated AC coil coming from the alternator, and everything else is getting power from the pink and yellow wires that are run though the rectifier and to the battery.

I'd leave the ignition coil alone and keep it on its own circuit.

Next step is to replace all of the bulbs and the battery with 12V versions. You should probably replace the horn as well, but if you're feeling lazy you might get a few uses out of it before it pops. :P

Here's where the options come in.

The easier option would be to replace the existing rectifier with a combined 12V R/R,ensure all your bulbs are LEDs, and then wire the headlight to run from the brown/white wire instead of the blue/white. You should get the total wattage draw low enough to make this work, but a voltmeter might be a good idea until you're sure you're not going to kill the battery.

If you want to get the full charging out of your system and still do a 12V DC conversion, you're going to need to pop open the alternator and float the ground on the white/yellow coil. You'll need a second R/R to make this work, but you shouldn't have any power issues.

And another option is to try an LED headlight bulb on the AC circuit along with a 12V AC regulator. The bulb will probably flash a bit (especially at low RPM) since LEDs only allow current to flow in one direction, but you might be able to avoid tinkering with the alternator if the power output from option one isn't cutting it.

In this method we are basically running everything on the single circuit? Just make everything LED and hope it drops enough to keep the bike charged?

So with this guy we are basically taking two independant circuits with two 12v reg/recs.  figuring out how to unground the current W/Y and using the ground back up to the second Reg/Reg.  Then running the powers out of both reg/recs to the battery?  Would it not work to simply run the two in circuit?  So hooking the floating ground to the reg/rec, the W/Y and the P together (creating the series), then Y to Y like always?

After she is up and running and I know everything works I will likely give this a shot.

It's possible this would work, but it might not. The problem with running the two different coils together is that if they're out of phase, the power from one might cancel out the power from the other. You can try it (it won't hurt anything), but you might be worse off than just using the first option.

So over the weekend I got to try and fire it, I got it to fire once after a bunch of kicks but never again.  When I pull a plug so that I can kick it over by hand and watch the plug I notice that it takes about 5-10 full kicks (which is about 10-20 revolutions) before the plug starts to have any spark.  After that it seems to keep sparking pretty good.  After it sits for about 20 seconds or so no more spark (I would assume thats expected as the condenser drains).  Being there is no battery is that expected?  I would think that it should only take about 2.  The RD starts up first kick without a battery but its got a fancy ignition.  If thats not expected does it sound more like a condenser/coil issue or a stator issue?

Sounds like stator possibly, the XL sparks every rotation, every time. The condenser is probably shot, as the stock Honda ones were known to fail.

My money is on the condensor not building park well then not holding juice long enough to get it to spark reliably. Condensors are usually cheap to swap, but also make sure you have a really good ground on it. I know on the GL I added a ground strap to the condensor as a bad ground would really effect the spark quality and they ground to the frame and that spot rusts etc so a wire straight to the frame ground from the neg battery terminal makes sure the ground is the best it can be.

Im REALLY Hoping its not the stator as thats not a cheap part on these motors.  It sounds like from what Spark said we have the same setup so if yours fires even first rotation then im assuming mine should to.  I'll buy a new consensor just in case, did you find a place to get them cheap?  This is good information thanks,

Side note, is a condenser a condenser? is there a difference in 6v vs 12v, amperage etc? Or can I really just get any condenser out there and swap on there?

I know on the GL I added a ground strap to the condensor as a bad ground would really effect the spark quality and they ground to the frame and that spot rusts etc so a wire straight to the frame ground from the neg battery terminal makes sure the ground is the best it can be.

I'll give that a try too.

Side note, is a condenser a condenser? is there a difference in 6v vs 12v, amperage etc? Or can I really just get any condenser out there and swap on there?

I'll give that a try too.

The condenser is a capcitor,
Ideally you get one with the same farads as original.

6v 12v is irrelevant, but the capacitor will be more charged at 12v than 6v. So the voltage will dictate how many microfarads the capacitor would be.

To few and the capacitor could fail.
To many and it won't have be able to recharge the coils effectively

The unit I bought came from eBay, relatively inexpensive.

If you're converting to 12v, the ignition will still run directly from the stator at 6v, so you should be fine replacing it with an OEM equivalent.

When i look up MT250 condenser on ebay, they are like $30.  You can get generic ones for like $10, so I was hoping to just nab one for like a cb550 and change the plug.

Alright so I swapped out the coil and capacitor and it seemed to help some but was still real odd. Went to check the points and such and noticed the flywheel was a little loose. Took it off to check around and realized that the keyway was borked, so keyway borked and loose flywheel = fucked up firing. Made a new keyway and will try to fire up tomorrow.

Not really, took it out during lunch and had a few issues.

First, it would mis pretty bad at WOT, but it was also running premix and the oil pump was priming so I think it was just that when it was hitting that like 15:1 it couldn't fire.

Swapped out the PreMix for regular once the pump was fully primed, now it just runs like shit.  Pulled a plug after a sprited run down the neighborhood and the plug is pretty black.  So Im going to jet it down some and see where that takes me.  Need to order jets, went to jetsrus but they dont carry the air jet, and mine is pretty wonky so I woudl really like to replace it along with a smaller main and pilot.

At least this is so much easier to tune that the KZ, that bike is going to be the death of me.  four fucking carbs, what was I thinking

Post by: JSJamboree on May 09, 2017, 22:53:59
Well the trip to Thakar was a failure. Thought it just needed a little tuning so I brought jets and never got it running well.

After getting home I oiled the filter (forgot) and BOOM now it runs like a fucking rocket. At this point all the lights work, the oil pump works, everything works. I need to throw some caswell in the tank for sanity sake. Things rattle and shake so lots of small touch things but it's ready to hammer now.

Yeah, we had it all the way up to 120 in KY, it ran fine but hated anything over 4K RPM, which doesn't get a 2t very far.  After oiling I went down to a 118 main. However the needle clip it all the way up, I think the needle in it could use some tuning. I don't want to drop the main any more because the plug looks good to a smidge lean where it currently sits after a chop at wot

Dang, with some newer style plastics yours looks like a much more modern bike.  I have a title so wanted to leave it street legal for resale sake.  There is a chamber like that on e-bay but its like $300 after shipping.  Do you know what it is? I would love to get more power, but dont want to spend that kind of money.

Its not a full restore but mechanically its been gone through and the motor is like new at this point.  This isn't going to let you down.  Asking 1750, I'll get some glamor pics up soon.

89ish FZR600, 89ish ZX7, 89ish GSXR750

Honestly its all about the cool looks than it is a specific bike or even being very fast, I just don't want anything smaller than a 600. Anything else i'm missing? Not looking for something rare or crazy.  They are still relatively inexpensive right now so I want to get one before the prices start to go up.

I love the looks and I believe they are the next wave of customs so un-effed originals will only get harder to find.  These earlier crotch rockets seemed to have alot of squid PO's so be careful there. 
The ZX7 would be my other first choice (besides my YZF750R, love love love)  but I haven't been able to find a decent one in awhile out here in the southwest.  I rode a buddy's ZX7 a bit back when and it was a blast.  I don't know much about the gixxers.   Check out Airtech-Streamlining to see what they make plastics for, it gives an idea of aftermarket support for the bikes and which ones were in demand for racing.

Quite affordable, though WAY less fun to work on than older bikes. Suddenly everything is packed in super tight and there's way more pieces to maintain (hydraulic clutch, disc brakes, etc). A total blast to ride, though, and way less money if you're willing to put in the time (PO couldn't get it started and didn't want to deal with taking the carbs off - I don't blame him).

Just sold my 84 vf1000f. Yes they are cool, it was fast and it was fun ' BUT pulling the carbs and re installing them makes me want to smack an old lady in the face. They are way more tightly packed and tough to work on than any bike from the previous 7-10 years that I've ever been around

100% agreed. When you say "previous 7-10 years" do you mean 74-77 or 2010-now? Just wondering if they made them LESS packed over time? I have a set of new jets coming in for the bike and I am not looking forward to dealing with them.

For an 80s bike that actually has a good dose of power and is SUPER easy to work on, the CX500 is pretty sweet. If you look at the power/weight and the torque, you're getting pretty close to a modern Moto Guzzi, though it does look like shit, and definitely doesn't have the "80s sports/super bike" aesthetic.

I was about 5 minutes away from picking up a non-running RG500 earlier this year at an auction in Seattle and I'm still kicking myself over passing it by.

I had an 02VFR800, it didn't have carbs but just changing the plugs required pulling the tank and 1/2 the body work off the bike.  Let alone when I had to sync the throttle bodies (might as well have been carborated).  I'll never own another Honda V4 again, and i'll really never own another VTec bike again.  There is an issue when its truly worth paying someone 800 just to check your valves.

Yeah, I sold my Triumph bobber on Ebay.  They paid the deposit, then paid the rest.  Once they had paid and I had the money in my account they setup shipping with company to come pick it up.  In theory it would have been fine but the company jerked the guy around and he ended up driving up from florida to pick it up.  I dont think that was an issue with the buyer or ebay or the process in general but a one off issue with a shipper.
