oversized valves for a wr450

2 posts in this topic

i had a question for experienced people out there, will i run into cam issues if i go 1mm oversized on some valve work on the head of my 2005 wr450? since i am in recovery mode this summer i want to port / polish the head and oversize the valves...if anyone has any experience with that could you reply...

and 2ndly, would it make a significant difference in power for the cost...

thanks
