1989 Kawasaki Bayou 300 Questions

Recommended Posts

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.

if its not useing oil [rings] then the most likely thing is the fuel/ air mixture screw, just back it down to snug then open a turn and a half or so, adjust from there. i have a 91 kaw 300 and that took care of the plug getting fouled.

as far as the wires go, check and see if the lites work, if not hookem up. if its charging ok . if the wires make no difference than it was an accesorry, winch or something. tape it up with electric tape then leave it be.

When the plug fouled I had the mixture screw turned out 1.5 turns from seated. Should I tighten it a bit to lean it ou?. I'm sure it uses a little oil as it does smoke a bit, not excessive though.

As far as those wires go, I installed a new CDI and new Rectifier and it is still charging around 16V .. Looks like the black/yellow wire that IS connected to the battery ground goes to the Rectifier. I can't find the other ends of these wires hanging out anywhere like where a winch might of been. Lights work.

The plug is new and is a DR7EA (hotter than the manufacture recommended DR8EA?)

One more thing to add to my post above, I just did a compression test and has 155 PSI of compression.

I guess my most important issue is understanding that vaccum operated slide and the correct location of that plastic cap thing that fits inside the spring. I wonder if maybe that needle could be causing an overfueling problem.

Hi, I am new to the forum. I just picked up an 89 Kawasaki bayou 300 4x4 and I noticed I have the same 2 wires that do no go to anything. I got mine started today but it only ran for about 2 minutes.

i think there are 5 slots on the needle, stay in the middle (3rd), thats probably where it is now. the overflowing will be the result of a dirty needle and seat at the float ...

if you think the needle and seat are good, check the tang tab on the float, it may need to be bent abit to close off the fuel. there should be a measurement in the carb section for float height in your manual ...

Hi everybody I bought a 89 Kawasaki bayou 4x4 and when I turn the key on nothing happens no lights light up or anything.its like it just dead but I put a new battery in it and I'm not getting fire from the spark plug. Any suggestions?

Have you tried to pull the spark plug out, turn the key on and test for spark by pulling the starter cord? There is or should be a compression relief lever on the right side of the top of the cylinder head. 

Have you checked the kill switch? 

If all of that checks out there is a neutral safety switch you would locate and test with a piece of wire. 

On the left side of the engine where the shifter is, on the top of the motor casing cover in that area you should see two wires coming out of the engine. One is red and one is a light green.  Unplug the green wire and put a jumper wire from that green on the harness side to the black (negative) terminal on the battery or any good ground point on the frame. 

Turn your key on and see what happens.

      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.

      Pushing the start button the engine turns and will forever without starting. But if I use the kick start it will start with one or two kicks everytime, any idea as to what is going on. New good battery and coil, I'm ready to try anything. It's a great bike, but this is getting anoying. Thank you.

      Ok, so I had no spark issues and foundy coil was bad. Bought a caltric coil, put it on and fired right up...for bout 20 minutes then it backfired once and again, no spark. I put it on my buddies 300 and it runs.  Checked my cdi the same thing, but still no spark. Now I got my old coil and  was ohming it and got reading of .01 on primary and 11.89 from POS to plug ( meter set on 20k ) new coil reads same primary but 12.83. what gives? It tests bad but runs my buddies 300, helllllllpppp

      Have a Bayou 400. sometimes when I press the start button i hear the solenoid click but the starter does not engage. Here is the strange thing though, when that happens if I kick the kick start just once then press the start button starter engages normally. Any ideas?

      Im looking for a atv fertilizer spreader that will spread bagged manure like Walmart sales. Does anyone have any recommendations or what have some of you used that will work with the bagged manure/fertilizer.

      I have a 2003 Bayou 250. Suddenly, it won't start with the start switch. No clicking, no neutral light on. It will pull start fine. The battery is new. Any idea what to look at first? Thanks.
