Xr/CRF100 engine compatibility 2004 in a 1994

Recommended Posts

Like the title says does anyone know if a 2004 CRF100 engine will fit in a 1994 XR100 frame. Came across a really good deal today and trying to figure it out

Crf 100/80 Xr 100/80/75 engines are all  interchangeable, with some own fabrication for the cdi mounting on older frames.

i know you already got your question answered, but for anyone else reading:

the engine had a minor change in like '92 or something. that's it. other than that the 75, 80, and 100 engines are all pretty much interchangable in the frames, like @waveline said.
