gpz 750 unitrak(hungary)

Hello
I welcome everyone Hungarian
unfortunately i don't speak english i write with google translator
I have a 1983 gpz 750 un-trak problem
I bought it and the valves clicked.
I thought I was measuring valve clearance
valve lifter no shim. !!!
how can i solve it
to calculate how much shim I need?
sorry for google translate

Yikes! :blink:
I hope the camshafts and followers (lifters) have not been ruined. I do not know of any way to measure that accurately. The best way may be to buy a full shim kit. If there is a friendly repair shop near by, or a friend with a stash of them, perhaps you can borrow a handful and return what you do not need.
Either way, I fear the only way forward is trial and error.
Before you start, be certain that the cams and followers are useable.

Some models have shim over lifter buckets
You have shims under the valve lifter bouckets.
To adjust the valve clearance you have to remove the cams at top dead center (TDC) of #1/4 cylinder.
750turbo.com offers a Service Manual that cover your bike and engine maintance.
Don´t Forget to reset the cam chain tensioner if you lift the valve cover!!!
