450r valves

[jmillermx144]

Can anyone tell me if the 04-05 kibblewhite valves will work in an 06 450r?

im pretty sure they will work i run 2007 CRF intake valves in my 04 TRX so should be able to go the other way

i dont think they will work, i know either the exhuast, or the intakes are interchangable. but i cant remember which

intakes are the same from all years, OEM 06+ are Ti and 04-05 are steel, i believe the exhaust are different sizes though
