Kibblewhite exhaust 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.
Needed new valves and springs for for my engine with putting a 440 big bore kit on kfx 400 have it in the shop right now getting all the engine work done so it is ready for the races hope she runs good with these valves that are said to be better than the titanium ones thank you motorsport team
will recommend to friend
Kibblewhite Exhaust Valves are top of the line,I've used before with v-good results.Highly recommend these for your next revalve.
this is a great product and i recomind it
Installation was tricky, being my first time and not having the right tools. Works great, starts and runs better then old valves. Would reccomend to someone with titanium valves.
istalled those dudes in my 702cc raptor, what a performance upgrade!
I have been recommending kibblewhite valves to anyone that has a fourstroke, especially honda's with their valve issues. using the stainless valves with the kibblewhite spring kit makes the bikes dependable, with no power loss. Easy to install.
These valves work great. I camed and bored out my LTZ400 and so far they seam to work really well.
The Kibble White Valves Are Some Of The Greatest. I Ride an 06 CRF250R and The Valves Wore Fast. These Valves Havent Wore At All! I Highly Recommend These Valves to Everyone!
OEM part numbers are the same from 07-08, but Kibblewhite lists different part numbers so basing it off of that, I would say dont use the 07 valves in your 08.
