I cannot get repeatable readings for the cam sprocket distance. The main issue is that the case has about a 0.2mm step at the parting line of the 2 halves. So obviously if I use just 1 case half, I get a rather small span on which to lay the straightedge, and based on that span my readings vary. If I use both case halves, I can get almost any reading I like based on where I set the straightedge.

Certainly neither method is repeatable within 0.25mm, though if I pick the exact same spot for the straightedge, I am usually within 0.05mm, so the repeatability issue is not with the operator or his equipment.

I am curious if anyone else has experienced this, and what you might have done about it. You'd think the surface would have been machined with the 2 halves clamped together, but obviously this was not the case (haha pun intended ...)

My solution has been to just use the same number of shims the factory did. The camshaft position is set by the chain housing, and since I have not switched cases or chain housings, I see no reason why the cam sprocket alignment should have changed.
