It is getting time to adjust the valves again (approx 20k miles). The last time I was in there they all checked out fine (approx 9600 miles). I know I won't be that lucky twice so I wanted to purchase a shim kit from Hot Cams but I don't know the diameter of the shims and I can't seem to find in searching through the forums. There web site only lists dirt bikes but I'm sure one of the kits offered (7.48 or 9.48 mm) should work. Any help would be appreciated!
