rising rpm

[JOMPPA10]

Hello again as you know i fixed carbs, but now i have new problem: when bike idles and little gas then off, but bike goes about 3000rpm and slowly drop to normal idle rpm
anyone knows that problem?

Running lean, idle circuit could be plugged.

I agree---running lean. Since you have fixed your carbs I think you have an air leak in a connection somewhere in the manifolds. How to find it is the problem. I use a way that is not the safest but is the fastest. With the bike at idle I use an unlit propane torch adjusted to a very low gas output and probe with it around all the connections on the carbs. If the leak is close the propane will get sucked in and your idle will go up and you found the leak.  Dave

I would of thought that a manifold leak would cause high idle situation all the time not just after acceleration, could be wrong though. My guess is fuel related.

no help with that(no leaking)  but i checked carbs diagcraphs and there vere some pinch holes and i used plasti dip to cure them. diagcraphs went more stiff.
i tested by driving and stange vibration in 3000-3500 rpm gone off, hope that helps a while.

and these carbs seem to be wery very sensitive to to fuel level

Hope that You or Randy can help me , because i have normal fuel seed from tank , no solenoid etc only one fuel line to pump,: do the pump act as fuel cut off valve?
And previous owner had put some  honda silencers to bike and they are big abouth 5inch x 20inch are these too big? sound is low but but.. are these silencers affect to
