Hey I have a 97 bayou 300 2x4 (klf300b) that i bought for 1000 last June and sunk another 1000 into it already. When i went to look at it, the seller had warmed it up before hand (he was riding it when I got there). it ran good so i bought it and took it home that evening... next morning it wouldn't hardly start. I discovered the carb was clogged, there was chunks of rust in the fuel valve, the choke lever was missing and other things. I have since cleaned the carb and replaced the fuel valve and gas lines and cleaned out the gas tank and cap.
Enough background on it, the problem is this: It floods if i push it past half throttle in 4th and 5th gear even going downhill and shifting correctly. It also has to idle and warm up when you first start it which is really annoying now that its cold... It also smokes blue smoke for about 15 seconds when started cold- does not smoke at all once warm but the exhaust still smells like burnt metal. A friend told me that it didn't have enough compression. I also found out that the valves are a common cause for low compression on Kawasakis.. I have never adjusted valves before- the most I've ever got into a engine was a head gasket on a riding mower so I'm new to this. My goal is to get this bike running and starting cold like a top- should i tear down and rebuild the top end? What should i try first? I tore the carb apart and rebuilt it and fiddled with the air screw and nothing changed. I also ordered a compression test kit that should be coming in soon.
Ive also considered just selling it for like $500 and taking the hit- Id rather not sink too much more into this machine.. lol
this bike! did this guy sucker me or what.. ok, looks like this means something is bent that I do not see or one rod is longer vs the other?
how long do you think this would last before it ripped into the tire? this is the right side, left side tire clears no problem
I can not find them on www.kawasakipartshouse.com
Following on from the brief interlude in the "introducing myself" thread....
In a nutshell, I acquired a YFM250 Moto 4 (1991) for cheap recently with the previous owner citing "no spark, needs a new magneto coil and I don't have time to fix it"... anyway I am dubious that the magneto/generator is the issue and thinking more along the line of ignition coil as after a clean up of the magneto I was able to get a rather decent voltage reading off the magneto with pull start and resistence readings seem to check out that the magneto is all ok (all 3 x phases = 1.2 ohms and no run to ground)
None the less I ordered a new Ignition coil and Magneto/generator coil and am waiting for them to arrive.
In the mean time I cleaned up the current Magneto, popped in a new battery and sparkplug, checked out all the wiring harness, all seemed good except I came across the "neutral switch" wire was broken.
After wiring up a new neutral switch wire, the neutral light now comes on (small win) and the starter relay (attached to rectifier) now clicks. If I hit the starter switch on handle bar the starter motor spins and if I pull the cord starter I get a spark on pull....YAY!! I'll try and attach a video below if possible.
So onto the starter motor. Starter solenoid seems to work A-ok, even if it looks crappy and starter motor spins as it should when I hit the start switch....but here is my issue.
When the starter motor runs it turns Cog #1 and Cog #2 (see photo below)....but the chain in the back of the starter which I assume is the timing chain, does not move and there is no apparent movement of the piston in the cylinder.
If I turn it by hand (per photo) or with the pull starter however the chain moves and the engine turns. However cog #2 rotates but not fluidly with the "Crank" (part I turn by hand) for the lack of a better word to use if that makes sense?
Is there a grub screw or similar on Cog #2 that fixes it to the center shaft to make it all turn when the starter motor is run? Could there be a part missing? Previous owner had the starter apart so could be possible?
The outer/front part seems to be on a key-way so not sure how to remove this easily to check how Cog #2 is attached.
What am I missing here?

I got this almost a year ago for $500.00 it was covered in a garage and owned by a 57 year old lady. She said she didn't need it anymore and wanted me to have it for my kids 1 of which is level 3 autistic. Ritual oil changes and yearly service. This was barely driven and when it was it wasn't beat on. All in all I got a killer deal on this wheeler and nothing is wrong with it. Starts and drives like its brand new.
