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?

      I have a 2020 axis 500 and I have replaced the TPS twice and the whole throttle body assembly once and still have code 122. I can barely drive the thing. It bucks and surges like crazy

      Hisun Sector 450 (2021) - help diagnose rear diff issue (short video included)
      By camojay
      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

      CFMOTO and Potential Motors announce industry-first ADAS technology for OHVs
      By Alex
      This is an interesting read. ADAS is main stream on cars these days. The technology looks to be headed towards UTVs and Off-Road Vehicles.
      Potential Motors and CFMOTO USA have announced a new partnership to integrate advanced driver-assist systems (ADAS) into recreational off-road vehicles for the first time.
      Sam Poirier, CEO and co-founder at Potential Motors, says the integration of its technology into CFMOTO’s vehicles will set new standards in the side-by-side segment. (Photo: Potential Motors Inc.) The partnership will first see Potential’s tech integrated into CFMOTO test vehicles. The companies will conduct extensive real-world testing at Potential’s purpose-built off-road proving ground in Fredericton, Canada, and CFMOTO facilities.

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.
