We had about the same problem with our Polaris 425. We put older race gas in it to get rid of it, and it never ran the same. Maybe check the fuel filters and spark plug. I guess if you run leaded fule in it, it might mess it up!

Mike,
Sounds like the pilot jet is gummed up or blocked in some way. I would take the bowl off and remove the jets to see what you find. The hole in the pilot is very small and it does not take much to clog it up.

Check your MAIN jet, it delivers fuel for anything above 1/4 throttle, your Pilot jet is for 1/4 and under. if this doesnt help let us know..

It sounds like you may have a plugged main jet. Pull the carb and remove the float bowl. Remove the main jet and the venturi tube below it and see if you can see or blow through it. A torch tip cleaner or a bristle from a wire brush will work to run through the jet to see if it is plugged. This is a common problem if a bike has set up for awhile at some point in time. If you have been in the carb, checked this, and have also adjusted the main throttle needle that travels down through the main jet (most needles have five slots in them - moving the e-clip down will make the bike run more rich, moving the clip up will lean it out more), then you may need an engine valve adjustment. Over time the valves seat into the head and clearances go away. Usually the bike gets hard to start when this happens. Look for at least .003 on the intake and .005 on the exhaust. I like to set the Kawasaki's to .005 intake and .007 exhaust, but it will run at 3 and 5. Finally another thing to check if the year Bayou 220 you have is equiped with this type carb, there is a cover on the top side of the carb with 4 screws in it. Under that cover is a diaphragm and the throttle slide. If that diaphragm is busted you won't get throttle response either, because it won't have enough vacuum to lift the slide up. If you spot this problem before the carb is removed from the bike, leave the carb on and replace the diaphragm. You may have to readjust the carb after replacing the diaphragm. I usually start at 2.5 turns out and go from there. If none of this helps you write back, because I have seen other problems with the 220's. I have a shop in the New Orleans area and work on these things all the time. Also let me know what the spark plug looks like if you post back. Hope this helps!

Yup, I too would say the main jet would be the place to start. I went to MMI years ago before I became a school teacher but I still remember some...If the jet is OK drain the gas and start fresh. This is a cheap, easy step in the trouble shooting process. Put in a new plug too so you can see what you have for a reading in the lean/rich category.
good luck....
P.S. Jammin, I think the ATV forum would go over well, I raced motocross for 6 yrs. and was disappointed that there was never anything out there for us quad racers...

keep up the good work..... Brandon

if the main jet is clear then dump the fuel and run pump gas like they like.Race fuel and atv's don't mix unless the motor is hopped up to the max.

here is the deal with your quad ( i have a few)once your carb runs on choke only, you basically need to ditch the carb. go buy a new one and slap it on. if you don't it is never going to run right. bite the bullet

Mike glad the info helped you out. The Kawasaki's are pretty good bikes, but they are 3rd on my list behind the Honda's and the Yamaha's. If ever someone puts up the right money that you feel comfortable parting with them, sell them, because they are prone to other problems down the line.
1) pick-up coils going bad (engine will sound like it's on a rev-limiter all the time)
2) the bearing on the driveshaft between the engine and rearend will go out. It is a sealed bearing, does not get oil from the engine or rear end and is the bearing IS ONLY SOLD AS A PART OF THE ENTIRE SHAFT ASSEMBLY, which is usually 200-300 bucks, and you'll have to replace the little pipe housing from the engine to rearend as well if the bearing seizes and grinds up the pipe.
3) the starter clutch and gear are of poor design. These are not part of the starter, they are behind the side cover. The 2 gears are heat "sweated" together from the factory and will eventually break free of each other, especially if you try to start the bike with low battery voltage and the engine "kicks" back a few times.

I don't sell ATV's, I just work on them. Honda is tops on my list because they are prone to less problems and have more aftermarket parts available for all of their ATV's. I always tell local hunters to look in the back of other guy's pickup trucks and look at what's there. Do they see old Hondas, Yamahas, Suzukis, or Kawasakis? I can almost guarantee you'll see more old Hondas. Just my honest opinion.
