Well done.

Did the shop leave as checked, or did they adjust to bring clearance back to about middle of the range?

Funny, I didn't even ask about that. The bill states they adjusted them.

why two measurements for each one?

ie: #1 exhaust 30...30 intake 18...18

wouldn't it measure just EX 30 .... or INT 18?

If they didn't charge you for shims i would assume they didn't use any.

Because our bikes have 4 valves per cylinder.
