1986 Bayou 300 fuel problems

Recommended Posts

Hi all...

Would like to pick your brains for help if I could?

I have a 86 Bayou 300 that I bought as a basket case.

Long story short...rebuilt the top end, fixed a BUNCH of stuff on it, rebuilt the carb...cleaned the gas tank and sealed it, fresh gas......ect.

Fired it up today and it runs!

Kind of.....

When I go a little above idle it starts to bog....The throttle diaphram slide is pulling up as it should but it flutters when it bogs. Ive adjusted the air screw for idle and it idles nicely. It has no affect on the bogging though.

If I hold the diaphram slide so it wont open up I can blip the throttle and get higher RPms with no problem. Let go of the slide and it bogs...

Sounds like not enough gas..but why?

May have to take the carb apart and blow it through with cleaner...might have a spec of dirt in it...or something.

It is a Keihin cvk32 carb.

Has anyone else experianced this?

Thanks in advance.

Tom H.

Hi:

Tks for the reply.

I figure ill take the carb apart again and dip it...I may have gotten a dirt goober in it somehow.

Plug is brand new.

I guess this is just the way it goes when you buy a basket and dont know what it was doing before the guy tore it to peices.

Tks

Well, actually I found the problems.

The air mixture screw had a cut o-ring and I didnt have the boot that goes from the back of the carb to the air filter box on.

Guess it needs some kind of backpressure in that area.

Dern thing runs fantastic now! :)

Tks All

Tom

      Hello everyone! I recently purchased this quad for a mere 300.00 and it is pretty clean for the year. I bought it from a guy who bought it in a storage unit. He didn’t know anything about it. I got it home and noticed it did not have an ignition coil for the spark plug. I bought the ignition coil, a new battery, new CDI box, new starter relay, new safety neutral relay, new carb and so on... I got it to turn over, but when I pull the plug and check for spark I have nothing.. it has a non factory starter button that works when I push it and turns the engine over no matter if the key or stop switch is on or off..not sure what that’s all about, but it does turn over..just no spark at the plug. Any help would be greatly appreciated! Thanks!

      Hi Everyone - Need some help.
      Got a nice little 220...clean machine. wiring is a mess. I have a diagram however, the one I have has 4 wires coming from the ignition switch not 2 like mine. So, I cant trace wires properly.
      There is a white one that runs to the Solenoid, and a brown wire...from the Ignition...I dont know where its supposed to go. Also, on the Solenoid, there are 3 wires..W to ignition, B to start relay and B/Y runs up to the front of the machine...and is not plugged into anything...and there isnt a "Mate" missing it. How do they plug into the 4 open shovels by the 20A fuse?
      I'm pretty sure my Lights and start switch/Lights are correct.
      Problem I cant get anything...new battery...cant get the start button to work, cant get any power to the lights or switches...so I know something is not grounded or..
      Any advice would be greatly appreciated.

      I had a quad fall in my lap a couple weeks ago. The only things I knew about it was it was a Kawasaki Bayou 220, was in pretty rough shape and was free. I couldn't say no to a fun little project. I've been looking a different ATV forums gathering quite a bit of info and decided this was the one I wanted to join.
      Thanks to this forum, I found the VIN under about an inch of mud and cross referenced it to be a '98. It had been sitting outside for at least 5 years and was told it ran when parked, but had no brakes. Squirrels or mice had been chewing on the handlebar controls and it's generally just kind of beat up.
      So far, I've gone through the carb (not near as bad as I expected), freed up the brakes (will probably need new cables), replaced the spark plug, air filter, petcock and put a new battery in it.
      The gas tank had been empty and looked clean so I put some fresh gas in it and tried to crank it today. I got a neutral light, but the starter button did nothing. I tried pull-starting it and it wouldn't fire. I checked the plug and wasn't getting a spark. I started digging and found some potential issues and some definite problems.
      I have a wiring diagram I found on here but it's just a picture or scan out of a book and hard to read. I don't see a reference to a black/yellow wire, which is my first problem.
      First, it that a factory crimp? One of those wired looks like it goes to the connector in the 2nd pic. Is that just a spade lug type connector? I pulled on it with some needle nose pliers but it didn't seem to want to come off. In the 3rd pic, should there be a fourth wire?
      I've read through and bookmarked the threads Andrew Baker and Arizona have going but I figured I needed to start with these obvious issues first. I have lots of pictures, so if there is something else you want to see, just ask. If I don't already have a pic, I'll take one.

      What's going on party people? First, thank you for allowing me the opportunity to be here. I recently purchased a 2005 yrs 450 and have yet to run the bike at full throttle. The bike fires up, idles, seems like everything runs fine except a little popping when you let off the throttle or until you hit 5th gear. It runs strong; no bogging or sluggishness until you hit 4th gear and open it up. Then it begins to act like it's out of gas or the about to be out. I can pull over and sit for 5-10 min and it runs strong again until you open the throttle. I have the carb off the bike to clean and wrote down a list of factory and what I found installed. I also listed other key factors and hope someone can help and explain. I'm new to the scene and have no prior mechanical experience but my theory is worst case scenario I have to take it to the shop anyway so why not learn. I actually enjoy it. Lol. Thanks a million. Hope to get back on the trails soon.

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.

      This past spring, Jonathan worked on a 1991 QuadRunner 250 that came with the fuel pump removed. We didn't find good information about connecting it online, so we made a video.
      Below is the link to watch Jonathan describe the connections on the Suzuki fuel pump. This applies to both the Quadrunner and King Quad ATV models.
       
      Hope you find it informative!

      Fuel line hose has a pinprick hole. And tips, suggestions or warnings about how to change it out would be appreciated.
