My bike engine experience is pretty limited. I've worked on solid lifter BMW engines a million times and have a good sense for what valve train noise sounds like loose and tight. I'm in my final tuning phase on my XS and I've got my valve lash set at .004" on the intakes and .006" on the exhaust. I can still hear the distinctive valve clack cold and warm, its not totally annoying but its definitely there. Do these engines just sound that way? I know on car engines if the lash is set carefully on the low side the noise is very limited or nearly gone all together. I fully understand it probably better to hear the valves then to risk them not seating fully reducing cooling and sealing ability. Thoughts?
