Product Description

Kibblewhite intake valves are a great upgrade from your O.E.M. motorcycle valves due to their superior performance and outstanding reliability.

All KPMI Black Diamond™ stainless steel valves are impregnated by a special German process to a depth of 0.002", with a surface build up of 0.0002". This "Black Diamond™" process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on Kibblewhite's computerized flow bench. Black Diamond™ Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics and will outlast titanium valves.

  • Type: Valve, intake, Black Diamond™.

Be warned
A friend of mine and I both installed the over sized intake and exhaust valves with great power results, but the down side is that we had too aggressive of a cam. We both snapped off one of the intake valves. We are both running 9i cams but if you are running a Hot Cam you will be fine. Other than the breaking valve they were great.
