Doing the shims on my Z650 (under bucket jobs).

All back together but when crank turned to TDC on 1 and 4, the inlet cam arrow is very slightly below the top rear face of the cylinder head, and the exhaust cam is slightly above the forward edge of the head. The arrows are the required 36 pins apart and the chain seams to be tensioned ok. The cut outs at the right hand end of the cams are halfway above/below the edge of the head.

Have I cocked up here are is this acceptable ?

Inlet


Exhaust

Is it my eyesight or does the top pic have EX on the cam sprocket? Is that right? The exhaust cam has the rev counter drive so the cams aren't mixed up but it seems odd?

Exhaust cam looks right, count starts at the next pin not the one arrow is pointing at. Inlet cam arrow should be pointing at the 36th pin, so if thats what you've got it is right.

Looks OK to me, the crank is in the right place, the pins on the chain can only go where they go, if you pointed the ex cam arrow at any other pin it would be even more out.

So unless you have a very worn cam chain - or a very worn front cam chain guide, both of which would allow the chain to allow the pin nearest the head to be raised a little.

I've seen loads as close as yours and never had a problem.

Thanks chaps for the confirmation.
