Mine were out of spec at 7,500 miles, the first check. They'd hardly moved at 19,000 miles. They needed adjustment at 35,000 miles. I was going to go to 65,000 before checking again but I had the airbox and carbs off so I figured I'd adjust them while I was halfway there. They had all tightened, but none were too tight (I could have skipped this adjustment, just barely). I set them nice and loose and I won't check them again until 90,000 miles or so. By then, I am certain that some of the exhaust valves will be on the smallest shims available and I'll just run it until it dies. Once it's dead I'll probably buy a Concours 14 or whatever the best S/T bike is at the time, since I'll be approaching 50 years old and retirement by then.
I've always needed to get at least 8 new shims when making adjustments. Mostly the exhuast shims move to the intake valves and the new shims go on the exhaust valves.
