Hi Gang, I recently bought a 02 wr 426 and I need to replace the piston... I'll save that for another thread... My question today is should I bother with the valves if they look OK. They are the original with about 50-60 hours on them. I believe these are the titanium valves and I saw the set of five would cost upwards of $350 bucks. I don't want to spend the cash if it isn't needed but I'm not sure the life expectancy of these titanium valves. Thanks for your help.
