Question

my pit bike high revs when choke is turned off! why?

Answer 1

IF IT THEN STOPS OR DOES NOT RUN VERY WELL, IT MIGHT BE LACK OF FUEL,CLEAN IT OUT or the choke might be sticking either way clean it all out with carb spray, and tyr again.

Answer 2

I'm thinking the throttle slide is not going right down so it is holding too may revs to idle. A sticking throttle cable or a carby out of adjustment is the common faults. Looking into the carby intake the slide should be almost fully closing the intake at idle. When you open the throttle then release it you should hear it slam shut and the twist grip close almost instantly...



If you suspect an air leak then light sprays with WD40 over likely places and when the motor alters revs then you will know where the air leak is...

Answer 3

You have an air leak



Check and make sure your hose clamps holding the carb on are tight. Check the intake manifold and make sure there are not cuts, rips or tears in the rubber manifold.



While you have the carb off, clean it. Clean your carb, carb jets, carb ports and set your floats to spec.



If the manifold is not damaged, start the bike up and check the carb body to make sure there are no cracks or worn out bushings. As the bike is running place your fingers over parts of the carb and listen for the engine revs to change. If they do, you have a worn part or cracked carb.
