Will a 2002 RM250 bottom end bolt into a 2000 frame? Cylinder/piston offf the 2000 bolt up to the 2002 bottom?

Thanks

Never tried it, but I seriously doubt it will. There are considerable differences motor-wise between those years.

You may be able to bolt the bottom end in the 2000 frame, with some modifications, but the head/jug is a whole 'nother story.

Yeah thats what I thought....I aint no zuk genius, but I thought at 01 they made big changes.

The engine should bolt in, but a '01 or newer cylinder will not bolt on to a 2000 or older bottom end.
