I just did valve adjustment on my new 400SX, and all four valves were tight!! I have aprox 20 hours on it,... I was contemplating waiting till after my next ride this weekend,..... Glad I didnt wait. The manual says valves should be adjusted every 15 hours.
This is strickly theoretic, but; could this be somewhat related to cam bearing failures, without sufficiant valve clearance, the impact during combustion could be placing an extra amount of pressure through out the valve train,...??? Ordinarily, this pressure would be transfered to the valve seats, where it should be.
Any comments?
