Intermittent running.  Sometimes she will start and run, sometimes she refuses to fire other than an occasional backfire through the carb.  Lately it won't start at all.  I've rebuilt the carb as it had some leaks.  Electrically I pulled the plug to check for spark... grounded it to the exhaust pipe and cranked her over.  Sometimes a weak yellow spark, sometimes a strong blue spark, sometimes none at all.  Seems to come and go.  Weird to me.  You guys have any ideas on where to start, or have seen this before?  Starting fluid doesn't help, won't fire at all when it has decided it won't run.

      Has anyone had a suzuki 230 quad lock the engine up?
      By docdoug72
      Has anyone had a suzuki 230 quad lock the engine up?  Its a well maintained bike, it locked up when my son was riding it. Pulled the plug, it has connected with the piston. I'm thinking the con rod let go.  I don't have a service manual.  Does the engine need to come out to check further?

      1989 Moto 4 YFM350ERW intermittent spark.
      By RGS
      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.

      Hello to all.

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

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.
