If You modify the frame it should.
Will a 94 rm 125 engine fit on a 2000 rm frame?
No, the crank shaft in the 450r is bigger than the 230f therefore the crankcases are bigger. The frame will not match up to the engine. only a engine intended for that frame will fit, however other year models will fit.
Unfortunately, a newer yz250 model engine will not be able to fit the frame of a 1991 model. These engines were designed to specifically fit the frames of certain models of the vehicle and are not universal.
Yes, you can.
if you modify the frame it will
The 1993 engine will not fit directly into the 1986 frame without modification due to a 1992 change in frame geometry and mounting positions.
Should fit no problem, ought to be the same engine that was used in the 85s
It will fit but you will have to change the K-frame or you could mount the engine in solid with engine plates.
A V8 engine
No a 125 frame is too small to fit a 250 motor but with a cutting torch and a welder anything is possible.
Yes, a 2001 kx100 engine fits in a 2001 kx100 frame like it was made for it
yes its is the same engine
