Can crf450r valves work in a trx405r

[scott84]

I am in the process of ordering new kibblewhite valves. Kibblewhite does not make valves for a 2006 trx450r, instead of ordering selling trx450r valves, they reccomend using their CRF450r dirtbike kit. I talked with one of the engineers, and he said it would be ok. Well I got home and looked at the crf450 specs, and the crf exhaust valves are 1mm more than the trx valve diameter.

TRX450r = exhaust valve 30mm dia.

CRF450 = exhaust valve 31mm dia.

Would this be a major problem? Has anyone got a solution, I am about to go crazy trying to figure out what will work.
Kibblewhite needs to go ahead and make a kit for the 2006 trx450r. It would take all of the guess work and research out of the equation!!!

Please let me know if you have any information on this topic.

Thanks,

Scott
