Here is the story. I bought the atv used it one week at the hunting camp no issues. I go back the next week and its working great, I cut it off for a break and go to crank it and it has no spark. I tore the bike completely down(all plastics off). All wiring looked good. I started cheap new plug coil. still no spark. Oh by the way no codes came up either. Next was a ecm because everything was testing out good (stator etc). I put the ecm on and boom it busted right off and was running great. New issue I noticed the wires from the stator going to the rectifier were scorching hot I mean burn you hot. I shut it down and started to research. I checked all grounds again. All grounds were good so I ordered a rectifier. Put the new rectifier on and same thing super hot. So I ordered a new stator and pulsar. Keep in mind the scooter was running great just wires getting to hot. The stator according to all the specs tested out good but I couldn't figure what else to do. So I put the new stator on today and I am back to NO spark. Someone please help I am loosing my mind. Thanks

You may need a new wiring harness. Seems like you have two wires in the harness shorted and they may come and go, depending on if the wires are tight or loose. I have seen wires burnt off inside the insulated plastic coating before.

      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.

      I am new to this site. I have a 1987 Suzuki LT230S Quadsport I think. Is there a difference between quadsport and quadrunner?

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      Does anyone have a recommendation of a really Heavy Duty ATV cover. I have bought several and they do keep the water off somewhat, but they are very thin and do not contour with the shape very well and water pools up in the rack louvers. I think i may be looking for a heavy canvas one, if anyone has a recommendation it would be greatly appreciated.
