Shims for valve ajustment

[Forden]

First check your clearances and verify what’s you have in the bike THEN order them if necessary. Depending on what is needed you may be able to move a few around and reduce the cost. However, DO NOT TURN THE MOTOR WITHOUT A SHIM IN EVERY LOCATION.

Well, I am that STUPID guy who did turn the motor with one shim out before I saw this. From what I can tell it scratched off a bit of the cam edge, and I *think I got out what little metal shaved off. Do I need to be concerned beyond that?

Sometimes learning is painful...

I've never done that.
Nope.
Never.
And even if it happened, I'd deny it.
Honest.

Don't worry about the edge being slightly bothered, they'll run for many thousands and thousands of miles in that state, almost as if it didn't matter.
Some say that a coin is an adequate substitute for a shim if you have to turn the engine over with a shim or two (or several ) out, while you figure out what ones you need to swap or get new. It's true.
