The carbs need 2 be in sync and he should check the intakes and vacuum lines for any leaks

I have the same machine only a year newer and I know if any of the lines

Are bad or not hooked up rite it will do that,

The mechanic told me all Kawasaki Prairies do that.If so,how does Kawasaki sell these Prairies?

I just think after paying $950 to someone it should run right.I trail ride & hunt,& my normal throttle is 1/4-1/2 & thats where the problem is.

My prairie rairley pops ... Only if really cold choked... The carbs have to be in sync if not it can cause

It to pop like that... Also any air leaks in the system will cause it...

I would take it back and demand it to be fixed rite..

If not I would take him to small claims Cort and get my

Money back or atleast u could get some of it back

I have owned several of the Kawasaki v-twins an never had an issue

And I ride with a v-twin club and work on several of the machines

If u want to go to kawasaki forum they can also tell ya about it

I have raced mine and trail ride it and use it for work and hunting..

I had a 04 Suzuki Twin Peaks(made by Kawasaki) that never did that.Am going to call Kawasaki Monday.Does anyone know the number to call to make sure I have the right one?(949-460-5688)Mechanic told me that was normal for Kawasaki to spit back through carb at certain RPM.

It's a common issue with the v-twinn ... But it can be fixed if you know what you

Are doing ... Or if you take it to some one that knows what they are doing...

It's usually a combination of carbs out of sync adjustment ... And a leak in a vacuum

Line or intake sucking air...

When you had the carbs rebuilt they may of not got the lines on rite or the are not sealing

The carbs also have to be in sync and drawing the same or it will also cause it to pop like that

If it was me I would find a mechanic that knows what they are doing on the v-twinn

Hello guys I am new here and this is my first post. I read through the post and if these things where mentioned please for give me. I have a few KAWIs. 02 Prairie the plunger on the enrichners stick. i realize you just had them cleaned. for $950 they had better been gold plated. timing chains are weak in those engines as well. all of mine will pop back some then i clean them. It is normal and very common, but to me not acceptable. pilot jets get stopped up way too easily. i always run sea-foam and it helps. Tech was right they all pop and spit and sputter some. 2002 had recall on the air filter system too. I can clean/rebuild sync prairie carbs with new kits for less than $200.00. $750.00 you wud of had to use on anger management! you could run crossover intakes and rejet pop is gone!

how about replacing the carb diaphrams?(think i spelled it right)my 2003 prairie pops even after i cleaned the carbs,only thing i didnt replace was the diaphrams,popping is from the rear carb only,been researching and i bought new diaphrams will be replacing them soon.i also run gas treatments and highest octane i can find,helps a little.

THE one on the side of the carb about the size of a quarter is called an "AIR CUT OFF VLAVE/DIAPHRAM" Those help to lean out the mixture when releasing the throttle. when you let off the throttle you hear a plop,plop,plop in the exhaust. this is afterburn. Unburnt fuel igniting in the ex pipe. I would look to Kehin for some replacements b4 i would Kawi. CROSS THEM OVER TO HARLEY DAVIDSON. LOT CHEAPER SAME PART.

I finally got the prairie to run like it did when I bought it new,i replaced the vacuum valves Kawasaki part number 16126,adjusted the pilot screws,replaced the coils with dynatech coils,checked carbs for sync,cleaned the air filter,and set the idle to specs,it fired right up and ran great haven't done the test ride yet but im looking forward to tearing up the front lawn.

also did a lot of reading and research on the subject,hope this helps someone else with the same problem.

      I just bought a rare beast!
      By kawasig
      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      2008 Brute Force 650, clutch is slow to engage
      By Coyote251
      I'm trying to help a buddy out with his bike (he's not really on the internet or familiar with these forums) and I'll admit that I am not super familiar with the transmission and clutches in these bikes. I owned a Brute a few years ago, but never had an issue like this that I had to troubleshoot.
      So basically my buddy bought a group lot of 650's to build one good bike out of. He got it all put together and has it running but when he pushes on the throttle the clutch doesn't engage till the RPM's are quite high and even when its moving it doesn't really speed up, almost seems like its in "limp mode". He's tried 2 different transmissions so I don't think that's the problem. 
      Is there any adjustment on the clutch engagement? Anything else I can tell him to look at? Let me know if you need anymore information if you think you can help.

      1990 Kawasaki Bayou 220 wiring issues
      By neilroy87
      I have a 1990 Bayou 220 that runs pretty well for it's age--needs a new muffler, but sounds tough.    Have had to start with a pull cord since I got it, and recently started troubleshooting the start button.  Finding a lot of information on this issue in the forum, but haven't been able to chase it down yet.  Got a new battery, new starter solenoid, and going to replace the starter relay this week, but not convinced that's going to do the trick, since I can't get the neutral light on when turning the key on.  I can start it by jumping the solenoid, but the 2 black wires to the relay do not activate the starter.  Bad ground or a short somewhere?  Is there a good way to just test the ground?
