Revving problems

[Ashtray 91]

1996 GS500E stays at high rpms when I bump the throttle or engage the clutch

Choke and throttle cables freemoving?

Yeah poured some d40 down them and I resealed the intake boots

[the_63]

Have you checked the float heights and idle?

If they weren't sticking they will now...

Yeah I'll check that out haven't messed with the carbs too much

[the_63]

I would check my float height (to make sure that they're not flooding), spark plugs (for signs that either cylinder isn't running rich), valve clearance (to make sure the intake especially is on spec.) then idle mixture.

Someone a little more experienced/finessed might have a different POA?

Could have a terrible vacuum leak.  "Hanging idle" is usually a dead giveaway, but this is also characterised by a return to idle after a few seconds.  If your RPMs stay high indefinitely something else is going on.

Take a spray bottle of water and with the bike idling mist the carbs.  If the idle falls, you have a vacuum leak.  If not, something else is going on.
It's the simplest test you can do, and any further issues can be compounded by vacuum leaks, so I'd start there.


What happens with the clutch?  As in it revs high when you pull the clutch in as if to come to a stop?


We could use more info as well.  Did this start recently?  Did you buy the bike like this?  Have you done any modifications to it recently?
When is the last time the carbs came apart?
When is the last time the air filter was replaced?

I bought the bike like this and it idles high when I come to a stop I put new fuel line and filter and the only thing I've done to the carbs is resealed the boots

Which boots did you re-seal?  The ones at the airbox or where the intakes join the head?  If it's the former, did you pull them off and check the O-rings behind the boots?  Those get dry and crispy and can let air in the system.  Other o-rings to go bad are the ones right on top of the carbs under the vacuum "nipples".  There's a great sticky on top of this forum that reviews the parts of the carbs.  Very helpful in identifiying potential pitfalls and weaknesses in these carbs.
