I have a 2015 Massimo 500 that idles really high and it will not let me shift into gear while it's idling. Not sure where to start. Also it will bog down and stall constantly. Starts right back up everytime. Advice please.

I don't know a whole lot about these Massimo brand, but it could be 2 things, a vacuum leak, causing excess air to enter the combustion chamber, or it could even be a electronic issue.

The bogging makes me think it's more of a vacuum leak, how I find vacuum leaks is I get a bottle of WD 40 in a trigger Pack, not a aresol can. And with it running spray around the injectors and lines and if I spray it in a certain spot and the engine speed changes, that's where it's leaking.

      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!

      Hisun 800 shuts down
      By DLJ
      Have a Hisun 800 it runs for about 35 minutes then stalls. Crank's over but has no spark. Let it sit for 15 to 20 minutes and it starts and runs again for about 35 minutes. Changed the CDI / ECU controller and still does it.
