Unleash your build with a CJR Performance CRF110F Race Head for your stock bore or big bore 110! One of the biggest restrictions we find with the 19+ CRF110F is the intake and exhaust port along with the OEM valve springs. With the new race heads you can bring up to +20% to +30% more power (varies for different build specs) through the entire rpm range and an increased RPM limit with top end power that keeps pulling strong. We now have two options available, our stock valve race head and 28/24 big valve race head. CJR Performance Stock Valve Race Head - Recommended for stock bore up to 147cc big bore kits. Depending on the camshaft, expect to retain good low RPM performance with a strong increase in mid-high rpm power and more available overrev.- Improved Polished Combustion Chamber Design- Eliminate
