I just bought a brand new 05 CRF250R and in the process of break in right now. Anyway I’ve never been on a 4 stroke and I have very little knowledge of four strokes. I have only been on 2 strokes. My question is are there any aftermarket parts recommended for CRF I have heard that I should change out the water pump and coolant cause the four strokes tend to heat up quite a bit and that they burn oil alot. Basically I’m not sure if should mess with it or add aftermarket coolant or like a boyesen pump any advice would be greatly appreciated.
