252.5 mile wheelie

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

No, a blown seal upsets the air/fuel mixture. A loose sloppy main bearing revs to the moon very easily because it is so loose.

Ohh, I see what you're saying now. I suppose the "blown" bearing works well until the balls begin turning into ovals...

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....

Sounds like you know whats going on.
I really wouldn't care if I dumped $1000 into it, at least I know what I got in the end.
I guess I should pull the motor before winter, and just tear it down.
Honda manual recommend you replace the piston every 30 hours, thats nothing, and I might as well start with a new piston, and replace anything else that looks questionable.
Then I could weld up the case around the clutch thingy (technical term).

The clutch not pulling in problem, I think will be fixed once the new handle and cable arrive. The cable is only moving about 1/2" down at the engine, and I have to pull it half way in until all the slack in the handle and cable are taken up.

I was just working on it tonight. I had gotten another surprise after it rained, and all the sanding the guy did showed up. LOL the armor all washed away.

I don't really care, as I was planning on all new plastic anyway. So I removed all the plastic, 400 sanded it, and sprayed a coat of clear on it. Looks freakin awesome (for what it is).

Second surprise I got was a s#%t load of grease around the front caliper, and the disk was completely covered in grease. OMG.
No wonder the front brakes felt mushy. I disassembled that, and cleaned it up, and now the brake works good.
I will be ordering another brake hose, and pads, again, just to start fresh.

All these things, are small, and I get them doen amazingly fast, as these trikes are so easy to work on.

Me and my 10 year old removed all the plastic, sanded it, and painted it in 2 hours, assembled back on the trike. Including taking apart the brakes.

Oh, and yea, the grills are removed already, and the originals were behind it. I flushed out the radiator.

I am not disappointed, it was sold as a rebuildable trike, and thats what I got.
It's a great starting point.

It was almost 100% functional, and thats a great place to start.
