l wacked a new 125 in the atomic today . Valves set at .03 inlet ex .04 . the engine fired up no worries only the tappet clicking seems to be excessive. lm going off 2 other lifan 110s l have that l run at the same clearances and they seem to be whisper quite. l may run the bike for a couple of hours and re inspect, but it seems odd. Any thoughts ??
