Turns out my quick tune up isn't so quick. I discovered that I was pretty much expecting the valve clearance checks to be a formality, but half of them need to be swapped out.
Intake: .08 (?!) .15 .15
Exhaust: .25 .20 .20
So I'm sidelined while I wait for my tools to show up, and then order replacements. The #1 intake really concerns me, enough that I've re-checked it about 5 times. When I rotate the cam with a wrench, it settles at an angle that might not be EXACTLY perpendicular to the shim- but a few degrees here and there isn't going to magically find me .07mm of clearance, is it?
When I bought the bike several years ago (12k or so) , I had a good tech give it a full service - I'll have to see if he made any notes about the valves then. He fixed and explained a lot of other issues to me, so I have no reason to think he did a substandard job.
