From the factory the CB450 / CL450 / CB500T Intake & Exhaust was set and listed at:
Factory: 0.03 mm (0.0012" in.)
Over here at Common Motor we have found through experience this value to be way too tight for these engines. We recommend setting your intake and exhaust clearance to:
Recommended: 0.08 mm (0.003" in.)
