CX500 1979.Hi - I checked and adjusted the tappet clearances today as by the Haynes manual no problem. However when I rode today the bike did sound a bit more tappety. I correctly set the clearances on a cold engine. The gaps were a little tight if anything before I adjusted them and the engine wasn't as noisy. Should I tighten the gaps a little to reduce the tappety noise. The feeler gauges did slide in with a bit of resistance after adjustment. The engine ran well, pulled well, accelerated throughout but was a bit noisier. Thanks in advance
