From: John on 14 Aug 2007 10:49 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!

Balance the carbs, check float heights. -- Message posted via MotorcycleKB.com http://www.motorcyclekb.com/Uwe/Forums.aspx/uk-classic/200708/1

Properly. They're probably gummed.

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 |
