'04 kvf700 missing at higher rpm

Recommended Posts

New member here and looking for help.

At 200 hours the check belt light came on. Removed the converter cover checked the belt and followed instructions for the reset. Now I have a miss that starts at 35 mph and it won't go past 50. It acts like you are turning the key off and back on. Pretty well ruled out carburation and fuel flow.

When I had the cover off I started the machine and noticed later a warning not to do that.

Just an update. Talked to the Kawasaki dealer, they suggested I try another ignitor. At $460 I hate to buy one just to try. They also said it could be the crank sensor or coils. I put a timing light on it and when it surges the spark goes out, does the same on both cylinders. Probably try the crank sensor first since it's less expensive.

Also talked to them about any possible problems caused by starting with the converter cover off. Dealer said it won't cause a problem electrically, the warning not to start is a safety concern.

Another update. Replaced the crank sensor, checked all the switches and sensors that feed into the igniter and the problems still there. Had the coils tested and they were okay. Ordered a used igniter from Powersports Nation for $80 bucks. Said they'd accept returns which I found very unusual considering it's an electrical part.

The igniter arrived yesterday, put it in and test rode. Really no difference. The surging wasn't as noticeable but still there and it only runs about 53mph.

      Figured I would post since I'm a new member.  Used to do a lot of desert riding when growing up but got out of it for quite some time.  Decided to start dipping back in and bought a Suzuki 50cc and Polaris 90 cc quads for my kids to learn on. Looks like this forum has lots of good information.  Hopefully I can learn and add to the community pool.

      I've owned bikes and quads for years.  Currently ride an 07 Raptor 700 SE.  My 15 year old son has a TRX 90 but he grew so much over the summer that he's outgrown it.  I picked up a project bike (1998 Kawasaki Bayou 300) for a couple hundred. It started but wouldn't run so I knew the carb was in need of attention.  Tires all shot (likely the original).   Pulled off the carb and put in the cleaner for a couple of days.  Pulled it out and cleaned it up and installed a kit.  Reinstalled and fired right up.  Now I've got to chase down some wiring gremlins from the previous owner. No ignition key just some toggle switch.  The wiring looks like it was hacked up by freddy kruger.  Got to tear into it after we get back deer hunting this weekend.  Anyway, that's my story and I'm sticking to it.

      Just bought this quad and it is in pretty good shape.
      It is missing a small plastic piece right above the headlamp cover right in front of handle bars. Does anybody know where I can find this piece?
      Now the CV axle. The left inner CV boot is ripped and wheel hesitates when making a sharp turn in that direction. I am trying to find a replacement or a fix, but have been recieving different suggestions for the fix.
      First one was buy a replacement CV axle. Second said to that the inner was it's own build and that if you ought a CV axle it would only e a half shaft. Just confused and need some guidence.
      Thank you guys!

      2000 Bayou misses out about half the time.
      I have done the following
      Cleaned the Carburetor.
      Replaced the plug and check the plug wire, its wire, Checked the plug boot it ohms out at 500 ohms
      Motor has 125# compression.
      I did find a barked place on the pickup coil wiring coming out of the motor case.
      I pulled the cover and ohm the pickup coil. It ohms at 470 ohms. I repaired the barked insulation and reinstalled.
      I replaced the igniter with a new one.
      I was told that the voltage regulator could be the problem so I unplugged it and made made sure the battery was fully charged and started it and ran it off the battery only. Still misses out.
      I added a jumper wire to ground on the igniter to make sure there was not a bad ground somewhere. I also added a hot wire to the igniter to be assured that the key or kill switch was not the problem.
      Nothing I have done has corrected the problem.
      Attached is a video. Note: the video camera does not show what the human eye sees. The timing light does not light when it misses but the human eye sees that it is dim during the times the video shows it not flashing.
      Any Help any of you guys or gals can give me will be appreciated.

      I have had problems with my artic cat 2004 400 4x4 manual transmission. It started with me having not riden in a month and when i started to ride gas came out of the overflow and a miss was going on. Cleaned carb and adjusted float and stoped the leak but miss was still there. Started leaking again 1 week later and went back in carb and found black rubber due to fuel line coming apart. Cleaned and reassembled. No more leak and cranks and idles fine but when riding still has small miss that you can hear sometimes poping back through carb. I have adjusted float, adjusted pilot screw, checked valve adjustment changed spark plug changed fuel line all seems fine. Could this be electrical??? When given almost full throttle out of gear it will miss bad is this due to a rev limitor or does this modle have one???? This is driving me nuts. Any advice will be helpful Thanks.

      This is my first post and I have some pics which I have attached.
      I have just bought a doer upper, Big Bear 1995 350 fwd. My first ever quad !!
      I took off the odometer cable and housing from the crankcase and there was no drive gear on the end of the cable. No sign of it in the part of the crankcase I could see.
      I am concerned the drive gear could have fallen down into the crankcase.
      Can I just take off the crankcase cover while the engine is in place to check if the cog has fallen into anything it could damage when I next start it up.

      I cleaned the carb out and set pilot to factory settings. idles fine but when I throttle the engine up the rpms do not back down very fast. does this mean I am running too lean? the cable does not appear to be sticking as I still have the side still off and can watch the cable.
      any help is appreciated.
