I've just bought a Cheep cheap GS500e but it will not idle properly even
if I get it warmed up and set the idle to 1200rpm but when I rev the
engine the idle increases to 3K and will not go down
like a stuck throttle cable but its not
if I then turn the idle screw down the revs slowly drop and then the
engine dies.
Help!

And clean the carbs out. Properly. They're probably gummed.

Balance the carbs, check float heights.

Air leak
Check that the vacuum take-off plugs are present on top of the carbs, if it
looks like bodger has been at the carbs take the tops off and see if the
small O ring is not missing from between the vacuum pipe and top cover,
check vacuum pipe from carb to petrol tap.
Check valve clearances, too tight will cripple the idle,
spec is 0.003-0.008mm
it decreases with wear.

Well the Carbs were full of muck and both O rings were missing.
Thanks
Next question
Has anyone done the valve shims on one of these mine are all tight I
don't think the exhausts were closing properly at all.
How do you remove the shim from the valve top bucket.

Thanks for you help

Your Haynes Book of Lies will reveal all. If you don't have a workshop
manual, get one.

Usual method for doing shim-over-bucket valve adjustments is to obtain
a special tool that compresses one or more buckets, then the shim(s) is
plucked out with a pointy thing or a magnet, etc.

Don't go to this website, whatever you do.

Especially don't watch this video:

You can take the camshafts out.
Buy the proper Suzuki tool.
Or grid a 6mm allen key like this

Once you have slightly opened a valve It will slip between the bucket edge
and the camshaft giving you two hands to fish the shim out with tweezers.
But while you have the cam cover off you should inspect the cam chain to see
if that needs replacing.
