Hi all, I recently adjusted the tappets on my yx 160, 0.003 intake 0.004 exhaust. The valves were fairly tight and I had to loosen them off to achieve these readings. The motor has slightly more compression now which is great but it developed a slight ticking sound from the head/tappers, which I don't quite understand. I warned the bike up for a minute or 2 before hand and both readings were pretty accurate, should I tighten them up slightly?? New oil?? I'm not sure, let me know!!
