Sounds like your high speed jet is still stopped up. You didn't tell me what type of carb you have on the bike but what you've got to do is the same. You must remove the float bowl, remove the main jet, and clean it out. Also, clean the very bottom of the inside of the float bowl.

Flushing a carb will not clean the jets. The reason is that fuel must be able to flow though the jet in order for any chemical additive to clean it. If no fuel flows through, no cleaning action is taking place. That's why you must disassemble the carb and manually clean the small holes in the jets.

If you need more specific instructions, I need to know exactly what carb you've got on the engine. Good Luck, Steve

What causes it to flood out and die


Are you running a carb? If so then check to make sure the choke is fully off, also check to make sure that the vent hose from the carb isn't blocked, and also check your gas tank cap. The easy way to do this is to crack it open like you are going to take it off but just enough so that there is no restriction of air into the gas tank. Leave the cap on the tank. Start it and see what she does. Sometimes what acts like flooding out is actually fuel starvation

Also, how old is the gasoline that you are using? If it's over a month old drain it and put in fresh.
Has your bike sat without running for some time? If yes then the carb could be junky and need cleaning.
Have you put any aftermarket parts on it? If you have changed the exhaust pipes, the carb needs to be tuned to the new pipes and if you went to a K & N style airfilter that is going to mean carb tuning as well.

Another thing is to check for vacuum leaks on the back side of the carb to intake manifold, and intake manifold to the heads. Spray bottle with water will cause the engine to react with either a increase in RPM or a decrease in RPM at idle

If anybody has been into the carb then you may have an internal vacuum leak in the carb itself.

Check all the simple stuff first and go from there.

1976 suzuki gs400 motorcycleengine idles too high approx 3000 rpm


there should be a knob on the left side underneath the carbs, it has a flexible drive attached that opperates the idle screw.
If that is gone there will be a screw in the middle of the carbs, but do not move the screws with the lock nuts. they are for carb sync.
Dont adjust with the cable, it needs a small amount of free play, so the cable dosent rev the engine when turning lock to lock

No sweat. Screw the idle mixture screw in until it "bottoms out". Do not tighten or you will damage the screw. Back the idle mixture screw out about three turns. Install carburator and check for proper operation.
When you get the bike running, allow it to warm up and then adjust the mixture for highest smoothest idle. Set idle speed to about 1000 rpm with the throttle stop screw.

My 2006 fz6 idles at 1120 to 1200 rpm is this the right idle rpm


ironmike_926 wrote: no it should be anywhere from 600 to 900

Absolute rubbish!! The idle speed should be between 1250 and 1350 rpm. If the engine is cold, the EFi will raise the idle speed temporarily to about 1600 rpm until it warms up (usually within 5 to 10 minutes at a standstill).

Your idle speed of 1120 to 1200 rpm is absolutely fine. However, if it drops any lower, you can raise the rpm by playing with the idle speed adjuster screw located on the gear-side under the fuel tank (can be seen without having to remove the fuel tank). Turn clockwise to increase rpm. You will find details on how to do this by selecting your manual from this link:

http://www.yamaha-motor.co.uk/community/service/manuals.jsp

WARNING: if the idle rpm continues to drop, you may have a more serious issue with the valve clearances, air-filter, or spark plugs. Consult a technical book (such as Haynes), or take it to your local Yamaha dealer to get it serviced.

Backfiring


Sounds like you've got a carb with a clogged jet. My guess is that the surging was a moment where the carb was actually operating well enough for the bike to run properly on that cylinder. Could also be a spark problem but you should be able to determine if this is the case rather quickly. I'd probably go ahead and replace the plugs if you haven't already...that could help...but my guess is still going to be carbs.
