motocross engine n spares?

[jay2]

My four stroke motocross bike has jus bent a valve and ive decided i want to fit a 125 or 250 two stroke engine instead of fixing it, I was jus wondering if any1 knows were i would be able to get an engine as ive had no luck so far

A while ago I was looking for one to try and shoehorn into my 125, they are pretty sparse on the ground... presumeably the engine is fairly likley to die before the frame is killed :-/

yeh the engines (nearly) always die before the frames for obviouse reasons, thats the problem ive got, i wouldnt mind buying a complete new bike but id b stuck with nearly a full bike of spares from the old one, n id h8 2 see it go 2 waste, especially the forks.

TIN posted a link to a second hand CRM250 engine (ok, not a dedicated competition MX engine, but gonna be better than a 125 )... forget what thread it was in.
