1981 xr250r engine swap

Recommended Posts

i know for fact a single carb xr500 will bolt in. the two bikes share a common frame. the only diff being the 500 has small amount of bracing on the frame. i put a 500 in a250 frame well over 10 years ago, any have rode the bike many miles. the problem with making it mx ready is the 500 engine is a major boat anchor. i recently bought my son a 1984 xr250, and it is hugely easier to ride. i hate so say this but look for a modern engine with modern frame wrapped around it. old bikes are still cool but they will never be competive
