Cool Mornings....No start

Recommended Posts

Cool mornings here  (high 50's -mid 60's).  The '02 300 Bayou has a replacement Chinese Carb that starts first or second hit at temps over 75 or so.  It wont start in the cool mornings.  Choke at any position, Throttle positions, turning over with the compression relief open a few turns, grinding for 20-30 secs, None helps.  Temp goes up, NO Problem.  Ideas?

Don’t like the Chinese carbs, never have. Any chance the machine has a warmer for the carburetor? Two wires that go in the back/bottom of the carburetor?

Chinese carburetors are not casted like a name brand carburetor. Things internally do not flow like they should.  I know for a fact that they do not perform like a name brand. They will start the machine and it will run at half throttle and brake up a bit and have problems starting etc. 

Your better off locating a used oem and rebuild it per spec including the jets and slap it on. Your chances of finding a used one in good shape is good.

Yep, it has the warmer built in.  I'll have to wire it to use the warmer.   OEM was out of my price range when I need it.  That is a target project though.

Thanks for the input.

Sorry for my confused answer.  Yes, the Chinese one has the warmer. My KLF is not wired for it.  I can probably handle doing that.  This replacement has been perfect to this point.  Runs well at all speeds and idles like a champ.

Oh ok got it now.  The warmer works well from what I hear but the temps you are talking about I don’t think warrant the warmer.   

Just curious have you pulled the plug to check the color ? Make sure your not having a blackened plug that may take a crank or two in order to get spark if that plug is oiled or rich it’s in a foiled state and could be your problem.  That could be from a rich mixture or bad valve seals or rings?  Heck I would even do a compression test to be sure.

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      I'm working on my brothers' 2002 Suzuki Vinson 500 . It sat for a few years before I got into it. I'm concentrating on the carb - I replaced orings, needle, etc. and soaked jets, bowl and anything that I could get off the carb that the solution wouldn't eat. I also removed the tank and flushed it with hot water - it's clean. The gas cap innards rusted away and the tank had a lot of rust and water in it before I cleaned it. I replaced the gas cap and installed a new fuel valve because the screens were broken in the old one. The bike will run but spits and sputters and backfires. If you "open it up" it falls on its face and stalls - but starts right up. Here is a link to an exploded view of the carb: Ohio Honda Yamaha Motorcycle ATV Dealer - J & J Motors - Kawasaki Suzuki Scooter Utility vehicle, parts, accessories, apparel
      Can anyone point me in the direction of the problem? It may still be a "clean carb parts issue" . My problem is that the parts list doesn't identify the parts to a degree that I understand. If you said" look at the pilot jet", I'm not sure which jet that would be....See what I mean? It'll run very good if I remove the air filter and cover the opening with my hand and part my fingers a little for the air to get in. Any help is greatly appreciated.
      Thanks in advance, Jim

      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
