since my 500 is in an 03 125 chassis I would want the same chassis for the 2 fiddy to keep the ergos the same. I really like the 125 handling for my type of riding.

I have a 98 cr 250 in a 05 crf 250 chassis. It is a fun bike. Wasnt that hard to do either. Mine took about 3 week to do, and my brother and I did his in 3 days.

Does anyone know the difference in mounts from a 250 to 500?

I just bought this 125 (actually has a 134 motor) but I don't want to cut it up for a conversion. yet.

I saw that one you'd got.
And the stamped frame.
Have you got 'provenance' on that - re : it really being a Lamson bike and the stampings being real?
If you have provenance, or can get it, it would be almost a crime to do anything to the bike other than bring it back to what it was when Lamson had it.
I'm not trying to be an arsehole, just hoping that something that could, perhaps be a genuine thing, doesn't get carved up. Over your way, it seems old CRs are a dime a dozen, and it might be more appropriate to build up a nice 96 250/ AF conversion out of something other than what may be a special bike.
Off course, it's yours to do what you like with.

I'd ride it, as a 134cc.
Would probably be a fantastic little bike, set up properly. The only thing lacking on LM CR125s was horsepower / a good power delivery. That may have been taken care of by the engine mods.

Hmm the 134 engine just may be what my 125 needs. If you do the conversion I'd be interested in buying the running gear from this bike.
