Once in a while engine will high idle and not go down till i shut it off for a minuite and restart. also it bucks once in a while when in slow traffic just off idle
Check for vacuum leak and fuel delivery. Fuel filter etc..
SOURCE: bike idles, but with a little throttle it jumps to high rev and wont come back down to idle
You need to oil your cables first....They make a gadget to help you do this...it clamps around the end of the cable, and you spray oil into a provided hole for a spray nozzle tube...Then see if the cables are unstuck by turning the throttle grip back and forth for awhile....start it and see if that helped....if not you may need to replace the cable(s)...I doubt that the slide in the carb is hanging up...or valve.If this doesn't work notify me.
SOURCE: Engine cuts out with clutch engaged.
is your bjke water cooled could have aproblem with that-its gettin hot-if air cooled carb may neede cleaning. the clutch is ok but indicates to me that that carb needs a low speed jet adjust also-do u have a clymer manual!!
SOURCE: Idles real high then dies and gets pipe red hot.
Sounds like you have too much fuel entering the engine .check the spark plug and see what colour it is .it should be a brownish pink .
SOURCE: cygnus x engine cuts out. as you come to a stop at
Check for any splits on the rubber intake sleeve.this is what connects the carb to the bike.If this does not rectify the fault then strip down and clean the carb jets especially the idle jet as it may be slightly blocked causeing such symptoms.good luck

Hello,
There could be several things that would cause your problem;
Wrong spark plug gap - too wide
CDI - The capacitive-discharge ignition uses capacitor discharge current output to fire the spark plug.
Bad gas
I would start by stabilizing your fuel to see if this is the issue. Buy a can of Sea Foam and a bottle of Sta-bil fuel stabilizer. Follow the directions on both of these items when filling your tank (use both together). Use premium fuel when filling up for this time. Run a full take through your system. When filling up again, you may use a lower grade of fuel if you want, but use the Sea Foam again. The Ethanol added to fuel these days can cause valve deposits that will lead to engine issues. You don't have to use the Sea Foam in every tank of fuel you buy - just use it once or twice a month.
Hope this helps. If you find this information helpful, please vote on this post.

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
