Remove the throttle stop adjuster and the air screw adjuster and spray carb cleaner in the holes.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Turn the pilot screw 1/4 turn counter clockwise. Check the float level. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower.Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Adjust the idle speed with the Throttle stop screw. This process should get you back on the road. A “very helpful” rating for this answer? Thanks!

Hi, my zzr 250 hadn't been started for about 8 months, so it fired up nicely with the choke on but once the bike warmed up I couldn't get it to idle once the choke was off, i tried more air to the carby...


Could be one of two things
1. The carbs are gummed up. Modern fuel will break down after only a few months. The idle jets are quite small and will easily become blocked. Strip and clean the carbs.
2. The throttle cable is sticky. Less likely, but possible. Make sure it opens and snaps shut easily.
What do you mean when you say you tried more air?

I had a simular problem on one of my other bikes. Bike will start fine, idle, rev up, but when you try to go it would spit and sputter. I found that the carbs were gummed up and not firing on all cylinder. easy way to check is start it up let it idle for a few seconds then get a spray bottle with water and spray the exhaust. if the cylinder is firing the water will sizzle if it is not it will just bead off. DO NOT do this when it is HOT this can cause many other problem only just after start up with a few minutes of running. Then you would know if you have some dead cylinders and then you can start back tracking from that because it could be carbs, plugs, coils, loose wire, but it will give you a start.

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.
