252.5 mile wheelie

[Dammit!]

What is the big difference, or differences, between 85 and 86?

Just a lot of small stuff. Nothing major. I just want my next 250R to be 100% compatible with my current 86 in case I ever need to swap parts.

Okay,
looks like your missing the Anodised black compression adjuster cover, this is a cover which is bolted onto the top outer edge of the reservoir, when you turn it it makes a clicking noise to indicate its hardening or softening your rear suspension,

when you take the cover off you will see a little spring, and on the end of the spring a small ball bearing, if you look closely at the pictures i sent ,you should be able make out the black cover with the silver philips headed screw in the middle, which holds it onto the rear shock reservoir.

AHHHH, thanks.

Maybe that was part of the damage when the chain came off, and hit the case.
I am missing the chain guard also.

Ok, now I need one of those, and the bearings, and screw.

The problem your having with your oil I believe that would be your water pump seal, I had the same issue with my 97 kx100, I drained the oil and coolant and replaced the seal then replaced the fluids and waalaa problem fixed, only thing is before installing a new water pump seal you always want to make sure the pump bearing turns smoothly because once you get the seal in on most bikes you cant get it back out without damaging it and I don't think you want to have to go back and remove the brand new seal to replace a bad bearing and end up buying a new seal again.
Just a little advice from my experience

Thanks, I will try draining out first, and see if it gets milky again.
If it does, I will replace the seal.

I plan on riding for about a year, while I do my 200X, then I will do this one.

I mostly got it for blasting across the ice, when the lake freezes.

Was this in NY man? Looks like a great candidate for restoration! Keep us posted!

I drove up to Mass. to get it. 500 miles round trip. It's in NY now

I will be restoring it, but first I want to finish the 200X I got a few months ago.

I will be sure to do build threads on both.

I fly R/C planes and did a few build threads on those, so I am familiar with keeping everyone informed, and then we can learn from each other as we go.

I just had a thought, we should do a 3wheel lake run here when the lake freezes.
Like a winter trike fest.

Usually there is a few oval tracks carved out also, and we can mess around a bit.

Thats one tuff look'n grab bar!

You should be able to hold on the rear shock resie with a couple of hose clamps too.

I'm down

That's a home made grab bar, with a solid steel tube for tools and stuff.
I don't think I will be keeping it, and get a PRM one.
Maybe donate that one to the 200x.

Ok, here are some more pics of what is going on, and some more questions. Everyone is probably at trikefest, maybe next year we will make the journey over there.

Pic 1, is that the standard radiator protector, or is that custom?
Should I just remove it?

Pic 2, the damage from the chain, just below the clutch lever.

Pic 3+4 the missing adjustment knob, there is scrape marks, so it was the chain that removed the knob for me,

Pic 5, does the position of the clutch lever look normal to you?
I think I need a new clutch cable, and lever, any recommendations?

Pic 6 one tie wrap...holding said resevior...

Tomorrow, I got to put close ups of the grab bar, lol.
Maybe a video of me going down the street.

I also here some clicking coming from the engine, kind of sounds like if the kick start is not all the way up, was wondering if this was normal, I have never owned a two stroke before. Maybe I'll do a video of the noise, but I doubt it will come through good.

There is definate wrench marks on the cylinder, so I am sure this engine has been apart before.

Starts on the third kick, with no choke, and idles great, has what I feel to be plenty of power. Lifts the front up, through the first three gears (thats all I got up too so far.)

I don't really have trails around here, until the winter comes. I have to pack up and go some where, and I want to fix all these obvious things first., and ease into it.

Motion Pro for the cable and MSR Pro Raptor clutch perch and lever assembly. Has an easy pull system built into it.

Looks alright. The problems listed aren't major but can be a pain. Yours would make a nice rider.

Dont worry about the rattle/clicking the motor makes, thats usually the Counterbalancer, all 250Rs do it to some extent.

And toss that radiator cover, looks like its attached over the top of the original one, IMO that thing will not flow enough air to keep the motor cool, and even worse if they are on both radiators. Nice bike for the price though, should be a keeper. HH

That's what I figured, I will be removing them, and I noticed looking from the other side, that the radiator is clogged in spots. I will be flushing it out with a mild pressure washer, and some chemicals. I own an HVAC business, and clean condensors all the time.
Thanks!

Where would you suggest is the best place to buy them?
Thanks!

Ok, motion pro for the cable, ordered it.

I'd worry ALOT about the motor noise. Sounds like the seller didn't disclose alot of problems. That noise could be normal or a warning of near self destruction. Of the few 250R motors I've torn into the counterbalancer bearings were always loose and the housings that hold it were cracked or worn out. The bolts themselves are another weak link in that counterbalancer. That milky fluid probably means a waterpump rebuild should happen. The clutch problem is most likely a worn out 85 style pivot and pushrod. The 89 250R clutch update kit will fix that up for about 100$, I hope the plates aren't smoked. Or it is possible that under that Epoxy the pivot lower surface is worn out from a chain ruining that engine case. Those radiator protectors are restricting way too much air, get rid of them and get some stockers. As far as it screaming, thats never a good indicator to go by with a 2 stroke. 2 strokes run there absolute best when there ready to blow up, especially when the crank bearings are gone. You could easlily dump over 1000$ into this R. Just trying to be honest with you as sometimes were all sorry we got too deep into something we shouldn't have started.

Glad to see another HVAC guy here, been hangin commercial duct for quite a few years now....

My friend's YZ85 has a blown crank seal, and it doesn't work for crap. What gives? It should be a screamer, right?!
