I have done quite a few valve adjusts on various bikes. The bikes that had shims I was always able to read the size on the shims I had to replace. Some were "shim under bucket" style and some were like our 900's and against the tappet. I hear people saying they need a digital caliper to measure the existing shims in order to know the size they need to bring it back to spec. Does anybody have trouble reading the shim size when you remove it? I don't want to buy a digital caliper if I know the size of the shim and I know the shims don't wear....the valve train wears since it is softer than the shims. My bike has 13,000 miles on it and I plan on doing the valve adjust fairly soon so I need to know. I'd rather not get it apart and have to scramble around looking for a way to measure them. Your help would be appreciated on this.
