High performance camshaft for the CRF150F and CRF230F. This is a great addition for the full on performance CRF150/230F. Higher lift and duration than stock (we do NOT publish our cam specs), this camshaft is a BBR exclusive. You MUST run our Heavy Duty Valve Springs with this camshaft to prevent valve float (and the resulting engine damage).Note: This camshaft only fits the 2003-2005 CRF150F or the 2003-2017 CRF230F. The 2006-2017 CRF150F is a completely different motor and will not accept this camshaft.
Note: This camshaft has been designed to work with the OEM Honda piston, or the BBR big bore kit piston, with OEM sized valves. Any other combination of parts will require that you manually check valve to piston clearance. This is typically done by assembling the motor with clay on the piston dome and carefully rolling the motor over by hand. The motor is then disassembled and the thickness of the clay is measured. We generally shoot for .050" of clearance on these smaller 2-valve air-cooled motors. If you don't understand this process you should check with a qualified performance engine buider. We can only support our own BBR products.
