Kawasaki Brute Force 650 Backfiring through carbs and exhaust

Recommended Posts

Hey all, I work for a fleet shop and we have a lifeguard ATV its a Kawasaki brute force 650. Its back firing through one carb more than the other one and back firing through the exhaust. Starts up and idles good, once you start giving it throttle it acts as if its starving for fuel. This thing gets tons of beach sand thrown at it 24/7. Things that have been replaced are:

both new carbs, new fuel pump, new plugs.

Things that have been checked: Compression is good - in range (high end of the range) also have ohm'd the coils and the resistance is within spec in the service manual. Fuel pick up is clean, no debris or restriction there. Does any body have any other ideas what it could be? Thanks for any input

      Can you believe this thing blew a new head gasket after a few weekend rides? Granted, it was beat on in a mud hole every weekend, but this is a new head gasket on a 400 Kodiak. Bummer.

      Hi guys new to this forum and thought I’d jump on as I’ve just bought my first quad a Kawasaki bayou klf300c 89 model. It had starting issues when I bought it so I’ve gone thru and replaced the cdi, voltage regulator and starter solenoid aswell as rebuilt the starter motor after all this it was still free spinning on electric start so I pulled the stator cover off to find the fly wheel wasn’t spinning so replaced the one way clutch bearing put it all back together and still not engaging at all. I’m at a loss and looking for some ideas on we’re to look next to solve the problem
      cheers Ben 👍

      I need help with wiring on a 1998 (I think, 10th digit of the VIN was W) Bayou. I'm not getting spark, I'm pretty sure it is due to grounds being off because the harness is pretty hacked as far as the electric start and charging system goes. I'm needing a good wiring schematic. I found one online and there are a few things that don't add up on it so I'm skeptical that it is really for my year and model. Any help would be appreciated. Thanks.

      Got a good deal on an 89 bayou 300. Couple questions. First is in the picture I have posted. Note the two wires at the bottom of the pic (white and black/yellow). They were not hooked up to anything and Im not sure if they are supposed to go to the battery or somewhere else and what they are for.
      Second question is I had the carb apart for a cleaning. The vaccum operated slide has a spring under the cap with a plastic clip that goes inside the spring. Is there a proper location inside the spring for that clip. Right now it is just below half way inside the spring.
      It runs alright but keeps fouling the plug. Pulled the plug off, cleaned it and dried it off and it starts back up but not sure how long before itll do it again, last time it was about 20 minutes of riding and it bogged out and wouldnt start.
