Hey, I've got an 89 fzr 600. It's got 42k on it and i got it at 37k. I was wondering what difference there would be if the valve clearances were out. Would I be able to notice it while riding? Or would the only way to find out be to use feeler gauges? Basically I'm trying to save myself the hassle of ripping everything apart if i don't need to or there is little benefit.
