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!!

get the motor really warm,go ride it.
and then see if tapping can be heard clearly.
but if you did correctly, and correct values, then all should be fine.

I suspect the valves weren't making any noise before the adjustments because they were too tight, slight ticking noise is normal.
