Hello,
New member, first post.
My racing club has several pit bike racing classes. I am wanting to build a bike for next season in the unlimited mod class. Question: Will a CRF230 engine fit in a CRF150R frame (big wheel)? The CRF150R chassis is excellent in just about every area, but I cannot run a water cooled engine. Therefore, I need a vertical air cooled four stroke engine. Will this fit in the 150R chassis? If not, any other suggestions? I am looking for the biggest displacement I can fit. I am guessing that is the 230, but am unsure. No matter what engine I swap in there, it will be rebuilt with more compression, and probably larger bore and stroke. Larger carb will be a must.
Rider will be intermediate/expert skill, 165 lbs. Will be raced in motocross and cross country.
Any and all suggestions are welcome.
Blessings,
Tim
