RM 250 Can't Find bottom end kit anywhere

[KYshooter23]

Okay, so I bought this 2000 RM250, I've never done anything besides basic maintenance really, so I bought this to learn. 

Im not sure if im posting in the right place or not, if not forgive me, but I paid $200 for it, wasnt expecting much, he said he thought it needed carb work, but took off the top end and the piston has pock marks, and is shot, the cylinder looks clean, now the crank has play in it (vertically) so I was told the crankshaft needs replaced, on another forum, problem is I cant find a crank shaft, a complete bottom end, anything, closest I can find is a rod, and I can find top end kits all day long, also the swingarm bolt is seized, so advice on that would help also, so if anyone could point me in the right direction it would be appreciated, I found a 2002 bottom end on ebay but i'm not sure if it would work or not, but I bid on it since it was real cheap and something happened and ebay shut down my account, so any advice?

I thought so, my friend said 2002 shoukd fit but I didnt think so, where do you think I should find the parts? I can keep sorting through ebay, but any part site I find doesnt have a complete bottom end or even a crankshaft

Thanks man there's a crank on here, I just gotta get this swingarm bolt out and the case split and hopefully get it done, I've been looking for weeks now for one, thanks for the help

good luck with the bolt - have you soaked it in anything ?

penetrating oil type stuff

Just some pb blaster, I haven't for a week or two though, i've heated it up with a torch, and beat it to death but it hasnt budged

I think the kx250 kit should fit your rm. they are basically the same bike and motor.

Okay I'll check it out thanks for the help

[S.O.A.N.Z]

yeah thats the worst bolt to get out once rust has set in

you need to keep re-applying that pb blaster

I had the same problem with the swingarm bolt on my 2006 RM250 the other day. I just beat and beat on it and after like a half hour of smacking it she finally gave way. Good luck man[emoji16]

I'm just gonna keep soaking it with oil, and im gonna invest in an air hammer, see if that works, I'll be back if I have any more problems thanks

I recently had the same issue.  I finally turned the bike on it's side so the PB Blaster could make it way thru the bearing spacers and with a little encouragement, it finally came out.

I have been trying to find anything that would confirm that.  Your not the first person I've heard say that.

Think it might be that year kx125 that was the same as the rm125 engine not the 250. Could be wrong tho

Buy a rod kit and have Your crank rebuilt, You would have to get back on eBay,  Vesrah rod kit 57.87, main bearing and seal kit 45.86, complete gasket kit 40.00  just 143.73 for all of it.

Then just the cost of the crank rebuild.

I'll see what my local shop says it'll cost, to do, but $143.73 isn't bad at all, thanks. I put it on craigslist for sale but everyone keeps low balling me, so I think I'll just fix it after all
