I know if it aint broke fix it until it is. : I'm going to take the cruiser to get the compression checked. Wondered what it should be? I'm not a mechanic so i'm assuming all the cylindars should be nearly the same, right? Also, i have never checked the valve clearance. Thinking about doing that, but i'm a bit worried with the whole shim thingy. What would be my best attack route? Or in other words, is there a standard clearance that each valve should have, or a specific #ed shim that should be at each valve? I did try the search junk! I've got a 95 with 143,000 miles on her.
