Kibblewhite Black Diamond Intake Valve
Corey in New York
lower compression ratio
I purchased both intake and exhaust vavles for my yz250f and i was impressed by the quality of them but because they are stainless steel kibblewhite domes the face of the valve to make it lighter weight. but because of this it added close to 2 more cc than the stock valves in the head of my motor lowering the compression ratio by almost a point.
