thanks Randombeat, would be nice of you

Checked the FSM and yes, they are independant, at least in my bike. (1980 kz750h1 ltd, inline 4 cylinder)

Hope that helps!

These shims are used to adjust the clearance between the valve assembly and the camshaft lobe. Each valve assembly is a slightly different length, and the seated (closed) position of each valve changes over time as the valve wears. Periodic valve clearance adjustment is necessary, and this adjustment is done by replacing the current shim with a slightly smaller or larger shim.

If you don't have the factory service manual, you should try to find one. It will have detailed instructions on how to measure and adjust the valve clearance using these shims.

upgraded my homemade valve tool with the ally bugger then disassembling has become easy as

valves, seats and sleeves are perfect

but stem seals are somewhat jammed from outside, i wonder if its usual for these engines? anyone in the know?

yup dohc ive heard about what the shims are for just wondered why such a big difference in them
i will sure check the clearences by a mockup assembling (head+cams+shims)

i do have a few pdf manuals but they are a real mess to look in, the text of poor quality and the pics are even worse
so usually i take my own pics while disassembling anything to use it as a manual on the way back

If you decide to check valve lash on the head sitting on a bench... do it with only one cam installed at a time and torqued correctly.
Never leave the head with the combustion chambers down towards the bench if the cams are installed.
Block the head off the bench by about 1 inch on each side. left and right and NOT anywhere near the open combustion chambers.
Turn only the one cam and concentrate on one lobe at a time... to the point of the largest gap (usually the lobe pointing away from the valve is OK).
If you mess this up with both cams installed ,,, and try to turn one cam at a time for clearance, you'll eventually have two valves in one of the same chambers trying to be open or open and I guarantee you'll bend one of the valves.

If you have not taken these precautions already... there is a good chance you already have a bent valve.
Especially if you were a bit careless and broke the cams off the head with it sitting on the flat on the bench.....

thanks for the hint mate, i'll bear that in mind!
