The exhaust valves won't stay adjusted for even 500 miles now. Either bad metallurgy in the existing head or valves, or I burned the valves and potentially damaged the valve seats when my bike went lean when my injector clogged up while the valves were too tight.

I could just replace the valves and hope for the best, but if I'd rather only take it apart once.
