2021 TBR7 Valve Noise
I have a TBR7, got it built and running, I have not put more than 25km on it and decided to do check the valves before riding it more. Entire process went smoothly, finding TDC on compression stroke and getting the valves within tolerance (0.04mm - 0.06mm for exhaust and intake). After putting the bike back together and turning it on, the bike starts right up but there is now a very loud clicking/tapping noise from the top of the engine.
The stock valves were super tight and there was 0 clearance at all, I tried to keep the valves towards the lesser end of the tolerance 0.04-0.05 because as they warm up I know they do expand slightly, but is there any reason to be concerned about the loud tapping. I know people say tappy valves are happy valves but is there a point when tapping too loud is bad?
