2004 kymco mongoose 50 No spark


Recommended Posts

I have a 2004 kymco mongoose 50 two stroke and it was a mess and it didnt run when I got it. There was practically no wiring harness and all of the wires that were there were electrical taped together. Long story short I ordered a aftermarket wiring harness (Complete Wiring Harness Electrics Wire Loom Kit CDI Rectifier Ignition Coil Magneto Stator For GY6) installed it and now I have no spark. Any ideas or help would be greatly appreciated.

The new harness came with new everything, stator, coil, rectifier, kill switch, cdi box the whole works. Everything plugged right in, most of the new stuff bolted to the factory locations. I never found anything for a rip cord. I finally go spark last night but not in a conventional way I suppose. Now that i have spark i tried to start it and it keeps flooding itself. So I adjusted the float and now it's not getting any fuel. Also when trying to start exhaust out of the carburetor really bad.15691720495593691804897636076143.thumb.jpg.13a41dc78aeb06241196b1c3d7810e3c.jpg

Maybe the float level was right when you first took it appart, it may have been dirt not letting the float needle to shut right , try to readjust  float level as it was before blow all passages with air and it should work fine again.caburetors are happy when  cleaned thoroughly . How's your spark plug you haven't mention it through out the entire post they're also happy when cleaned or much better when new. Nice ride BTW,that frame looks neat!!

I re adjusted the float last night and cleaned the carburetor again just to make sure. The spark plug is new. Pulled the reed valves out and one had a piece of gasket maker in it forcing it to stay open. Put it all back together and still nothing. I am getting fuel and spark, but the spark is looking weak now😡.

Ok make an old school trick to discard possible trouble  sources when igniting motors. Pour a dab of fuel through spark plug hole, screw the plug back in and whith full open throtle try to start it over.Now if that doesn't work ,now you know fuel is not the issue ,it's got to be a spark problem ,  keep on posting the results I'll be aware of your findings. Good Luck !!

      Hello,
      I have read many forum topics on this matter but have never found a similar problem. So i bought a cheap ass quad thats got all sorts of parts on it. It's a 1997(if you look the date on frame) Kawasaki KLF(Bayou) 300 EUROPEAN Model (atleast I think, since I'm from Europe), the engine is 1988 if I'm not mistaken and the CDI is 1995.-2006. ( 21119-1447, 6pin ). My problem is that I don't have spark. I would diagnose the issue but connectors from CDI to wiring harness have almost all different colors and I'm not sure if they are connected correctly (pictures below). Pickup coil is putting out around 400 ohms and is pulsing. CDI is being fed 12v by one y/r wire that is coming to connector and with 12v to one gray wire which is coming from ignition switch ( quad actually doesn't have ignition switch so I'm not sure if gray should be supplying power or not). Stator looks good cause when crancking all three yellow wires put out around 5v AC. Neutral light is also on which means the switch should be ok, if it even matters. I know it's not the ignition coil since I get no power nor any kind of pulsing to G/W wire that is coming to it ( and I even put another one on there just to check an it ended with the same result). I'm nowhere near proffesional around this type of stuff so any help would be amazing.

      Hey just picked up another scrambler 850 was told the tps was bad.  This atv has been beet to hell.  Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
      my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it.  When I bought it it would pulse and smoke black at idle and die with throttle.
      New tps installed and it won’t run period.  I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps.  Is this normal and if so how should I celebrate it?

      Hello everyone,
      Im new here, this is my first post and Im trying to figure out how evrything works on this site so I please let me know if Im doing anything wrong.
      I have a couple Yamaha's but this post is in regards to my 02 Grizzly 660, I have an electrical draw somewhere that is taking my new battery down rather quickly. I have tried to locate any short by checking each circuit but was not able to locate it that way. Im installing a battery cut off switch which brings me to my first question, dont these switches usually go on the Negative terminal?
      My next question is, can anyone tell me if this year and model has any history of electrical shorts that might help me locate the culprit? Any help would be greatly appreciated!
      Finally, Im looking forward to being a member of this site and hopefully helping others as well as learning some things myself, so greetings to all!
      Best wishes to everyone!

      I'm having a problem getting a CDI unit that works. The parts list calls for a  4XE-85540-00-00 CDI unit. The one currently on the ATV works but there seems to be a problem with the spark advance curve. It will idle fine an rev. to about 1.5K then  starts bogging down sputtering, popping and basically running poorly. If you can get it above 2200 RPM it runs better. I have ordered and returned about 5 replacement modules that will not work at all. The unit currently on the bike has no part numbers or identification other than a Mitisibuchi logo. I am wondering if anyone else has experienced similar problems with replacement CDI's and if so what is the fix? So far I have not found a replacement CDI that will supply an pulse to the Ignition coil.
