Ok guys and gals this one has me stumped. I was working on my buddies quad that was smoking alot on our ride over the weekend and i was doing a compression test on it and came up good on his. And my quad was right next to it and i couldnt help myself so i did a compression test on mine. My fsm says 100-128 is good. I do it on mine and i get 140………….thats where i try it 3 more times and its 140 everytime. Is it possible for there to be that much soot built up in the combustion chamber? Or would this mean i am high compression or what? If someone worked on this quad they are a magician because all the bolts dont have any marks on them and i would say i am positive it hasnt been apart its so clean. But that high of compression has me stumped. Any info would be highly appreciated!
