If you take the bike apart before you damage the seats, you probably won't need to buy a new head.

Installing the Kibblewhite stainless valves and ti spring kit is the way to go for longevity. :cool:

I have an 02 yz426 with ti valves. Can I go back to stainless for increased life or do I have to keep buying ti?
