Just bought gently used (16 miles) Massimo Buck 450 and I'm having the idle won't run when you step on the gas issue???   WTF??  Is it in fact the exhaust sensor??

      Challenger 750 flywheel issue
      By Croppy38
      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.

      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

      Coleman 400 UTV fuel issue
      By weasel
      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.
