Installation Note: This kit will NOT work with the Honda XR/CRF70 or other big port cylinder heads. It is designed for the tiny combustion chamber of the OEM Honda XR/CRF50 cylinder head. The flat top piston dome will result in an extremely low compression ratio when combined with the XR/CRF70 type cylinder head. The result is a motor that makes less horsepower than stock.
** Kit should be installed by a certified mechanic to ensure proper function.
Improper installation could result in catastrophic engine failure.
