I did the valve clearances on the Kwak at 12,000 miles and they wear all tending towards being tight, but they were fairly all over the place. Trouble is there's no way you can really tell till you get in there, Ricardo, what incriments do you have on your feeler gauges, I had to double them up to get the right measurements i.e. 0.08 + 0.04 to get 0.12. If you only have 0.05 incriments it can be a bit tricky to tell exactly what measurement you have.
Tight clearances are not a good thing and should be taken seriosuly
