Shim Change and Mileage

[unfazed]

Foolish thinking and false economy for the sake of a few hours work. I have checked many over the years and whereas most are fine there have been the odd few which are tight and loose. A Fazer 1000 I checked recently at 20000 miles required 9 to be changed, 8 were tight. Had to buy 3 shims and managed to get others close to specifications by swapping them around. My own 600 needed  three changing at 50000 miles and will be checking it again shortly before it reaches 80000.
Alway work on the basis: A loose tappat annoys the rider, a tight on annoys the engine.
