Hello everyone, any help/advice would be greatly appreciated. Helping my father with his 2018 massimo 500 4x4 side by side. He uses it to feed all the horses and cattle. As of now the only way I can get the dang thing to start is to take the fuel injector and hold it about a inch away from the head boot, start turning it over and as it starts up I just press the injector all the way in. I thought this was a air problem so I replaced the idle air valve. I also replaced the fuel injector, spark plug, and adjusted the valves not that long ago. I thru a new computer on it as we had a extra on hand. It is running pretty good just won't start without that trick. Does anyone have any ideals what the problem may be?

      2017 Challenger 500 No power on take off or hills
      By great8redsfan
      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

      Start relay
      By donwan
      I have a part that fell over to the exhaust and burned the harness up. I can't figure out what it is. Does anyone know what the start relay looks like? The part I can't figure out has 4 wires, a red power, a green and brown wire, a black and unsure what the 4th color was. Anyone have a clue?

      2010 500 - New Carb- Hesitation
      By Buddee
      Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?
       
      Any help appreciated!

      Massimo Buck 400 overheating
      By KMart
      I have a Massimo 400 Buck that overheats and the antifreeze blows out of the motor everywhere! I don’t have to be doing anything but just driving through the field.  It only has 26 miles on it.  I don’t think the fan is turning to cool the motor.  Any ideas how to fix this?
