I have an 02 eiger and im trying to adjust the valves. Have it all taken apart. The inspection hole and mark on the cup indicates that the piston is tdc. Where does the feeler guage go?? Book say it goes between the valve end and adjuster nut, but actually the nut just holds it in place do they mean the screw? Is there usally any slack here. Ive read that adjusting the valves helps if they are out of adjustment which i think might be my problem. I have 1100 miles on it.

 

let me know if that solves the problem. my hasnt made the exhaust noise since it was below freezing
