I'm not familiar with that model, but typically the keyswitch connects to the ECU so switching it off shuts off power to the ECU which kills the spark.

Some older small engine type stuff (stuff without a computer) it physically grounds the spark plug wire. Energy prefers the direct path to ground without having to jump the spark gap and the engine dies. This is still how lawnmowers, chainsaws, weed whackers, etc work today.

      2014 Bennche Bighorn 700 Won't stay running
      By Hutch
      Okay everyone, need some help here. I got my 2014 Bennche Bighorn 700 from my father inlaw. He has had it since new and as far as I know never had any problems with it until recently. It began with it being hard to start and having to give it some throttle for it to start up. Then it wouldn't stay running once it did start. If you go to start it, it will fire right off and only run for a split second and then die. If you give it some throttle it will start and stay running as long as your foot is on the pedal. While it's running its pretty rough and backfires. Here is a list of everything I've done so far. Initially I checked compression and it was low. I changed the cylinder, piston and rings. Took the head apart cleaned and laped the valves. Checked timing a few times. Adjusted the valves. New spark plug. Checked the air filter, it was fine. New battery. Changed the fuel pump because of a broken fitting. Changed the fuel filter, lines and fuel injector. Dumped the old fuel and put new in. Changed the air idle control, TPS, MAP sensor, Voltage Regulator, ECU and harness. I was getting codes 31, 107, 113 and 122 on the display. Once I changed the ECU no more codes have been displayed but still have the same issues. All fuses look good and as far as I can tell Grounds are good unless there are some I can't find. I'm at a loss here. Not really sure where to go. Compression was better after everything I did but I don't remember the numbers. I'll have to check it again if someone thinks that could be the issue. Any help would be greatly appreciated!

      Can-Am Ryker Accessories Question
      By hetovi
      Hello everyone.
      I recently bought a Can-Am Ryker and I'm looking to customize it with some accessories. I’ve seen a lot of options out there but wanted to get some recommendations from fellow riders.
      What are the must-have accessories for comfort, style, or performance?
      Specifically, I'm considering a windshield and better footpegs—are these worth the investment?
      Also, any thoughts on storage solutions like saddlebags or rear cases?
      Would love to hear your personal experiences with any mods you’ve done.

      2013 hisun 500 efi utv. No fuel, no spark
      By Robby
      Hello, I have a 2013 500 utv hisun. Was running ok and cut out while parked. Bike will not start now. It turns over, but won't fire. I have no spark and no fuel. I replaced fuel pump, ignition coil, spark plug, cdi, voltage rectifier and all the fuses and relays. Could bad stater cause no fuel because I can't hear the fuel pump priming. Any info on where to start looking for problem.

      Hey there,
      I’m trying to find a CVT (variator) for my Tracker Off Road 800SX Crew. Do you happen to have one, or know where I can get it?
      Also, if you’ve got any other parts for this model, I’d love to hear about them!
      Thanks a lot!
