Hey everyone. This is my first post and I hope you all can help out here. I have a 2016 Massimo 500. I'll start out with "it is a beast" I have worked the crap out of this thing and it keeps on coming back for more. Never had an issue except one battery replacement and this cold starting thing.  When I start it up, summer or winter, it requires being in neutral, pre-loadiung the fuel by pumping the gas pedal (like an older carb model) and then once it starts, I have to maintain 3000 RPMs or more for at least three or four minutes before it will idle on it's own.  After that, it will idle for as long as you ask it to.  Any input?

  • Alex changed the title to 2016 Massimo 500 won't idle at start up.

      Got a 2021 Axis 500.
      I'm needing the head bolt torque specs.
      Manual states 38nm.
      But saw a video Hisun put out on YT for a 550 stating 50nm + 45° turn of wrench. Didn't think they would be that much difference on a 500 and a 550.
      Seen another YT video on a 2013 500. He did 38nm.
      Really only want to do this job once and done. And done correct.
      Anybody got the answer?
      Going to start this rebuild in a few once this weather brakes. Flooding and then snow and cold here now. But spring is around the corner and the wife has to have this fixed or a Honda pioneer may be parked in driveway soon. She has to be able to ride.

      I own a 2017 Challenger 750 and had the key way snap at the flywheel. It was removed and cleaned up and then the  flywheel was put back on with a new keyway. It snapped a second time so the flywheel and keyway both were replaced. They both seem to fit nice and tight. Put it all back together and it snapped again. I have no idea why it is doing this.

      My buddy has a ut400 that the forward gear keeps popping out of gear. She only has like 400 miles on the odometer .the shift cable has been adjusted and the shift lever has been updated / modified. All other gears are good. Is there an internal detent cam or something that wears out or shift fork that can be replaced ? Or is there some other magic that I can perform ? Looks like the engine needs to be split.

      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work
