Most likely your slow (idle, pilot, whichever name you prefer) jets are plugged up in your carburetors. If the bike was stored improperly, or old/dirty gas was in the tank, these jets get plugged up pretty easily. One if not all are probably affected. The slow jet is where your bike pulls gas while it has a closed throttle position. Its the smallest jet in the carbs. When you twist the throttle, the needle (blocking the main jet from being used) opens up and allows gas to pass it and up into the vacuum of your carb and into your engine. If the idle jets are plugged you will usually notice that if you give the bike throttle it will run great in the higher RPM (3000+) but will die and be "glitchy" or boggy when going from no throttle to open throttle. You can try to cheat a carb clean by getting some carb cleaner and spraying that down the carbs, and using seafoam or equivalent to get those jets clean, but its always a better bet to see whats going on inside and clean those things so you get your throttle response back. Goodluck.

What's the best choke setting for starting a cold generator


Full choke to start, open choke partially immediately the engine starts to where the motor runs smoothly, continue opening as soon as you can while keeping the engine running smoothly. Be sure to open fully before leaving the unit, running it with the choke partially on can cause a rich fuel condition which tends to wash the oil off the cylinder walls and it also dilutes the oil with gasoline.

I have to keep choke almost completely on to get it to start, runs a little bit and shuts off.


you probably have a dirty carburetor, the choke causes a vacuum and keeps the motor running, when you take the choke off there isn't enough vacuum in the fuel line to keep it running. a very common problem with todays ethenol fuel. have the carburetor cleaned completely and it should solve your problem.

Last time I STARTED MY VSTAR 1100 I CHOKED IT FOR 10 SECONDS ON HIGH THEN MOVED TO MEDIUM CHOKE FOR 4 THEN TOOK OFF AT NO CHOKE. 2 WEEKS LATER. I started up bike Choke on high bike barely wanted to idle...


Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck

FZR 400R Deltabox Exup. wont idle properly Howzit everyone. I have a "small" issue with my FZR 400R Deltabox Exup. So it doesn't want to idle properly(the moment I reduce the idle speed to any point below 3000rpm it continues to drop and dies) and also revving the bike it bogs around 6000rpm doesn't go any higher. When restricting the airflow through the airbox it revs better(all the way to 14k rpm) but still doesn't want to idle as the revs then hang on it's way down. I suspected this was all caused by an air leak somewhere, sprayed some quick start on the boots between the carbs and the intake as well as between the airbox and the carbs with no jump in the revs. Nevertheless I sealed the boots just to make sure they aren't the problem. I then stripped the carb and cleaned it properly, put everything back together, sorted out their syncing and reset the mixture screws to 3.5 turns out(which sounds a bit far out, but thats what the manual said-since then I've tried everything from 0.5 to 4 turns out with no significant effect). Then the cylinder started acting up(not firings- a different cylinder about every third time the bike was started) I then replaced the spark plugs with new ones(NGK cr9ek as per the manual) after that cylinder 1,2 and 3 was firing, but 4 was still dead. I Replaced the coil, leads and caps, still not firing. I checked the compression, which was fine, I checked the valve clearance (cylinder 4 the one intake valve was way out of spec, so i replaced the shim), still not firing. I've got no idea what else could be the problem or what to check next. PS. When i pulled the spark plugs(both new and old) they where burnt black so I'm not sure if my jetting could be out of spec perhaps?
