Recently acquired a 2017 Challenger 750. Previous owner ran it low on oil so I had to do a top end. Starts and runs but it seems to be running very rich. There isn't too much information available for troubleshooting the EFI system. Air filter is new and I even tried running with it removed with no change. Some of the parts are relatively cheap, so I did replace the IAC and the MAF sensor. Could this be related to the TPS sensor or which direction should I head in next? There doesn't seem to be any adjustment on the TPS and I have read something about a WOT ECU reset but that didn't change anything. 

Thanks in advance

      2022 t-boss 760 oil filter
      By Aaron Colona
      Just bought a brand new 760 about a month ago. I'm at 20 hours which the book says is when you need to change the break in oil. 
       
      I must be crazy, but I can't find the oil filter. I've googled a million videos...everything seems to be 2019 or lower...and/or a 550.  They all show the filter easily seen by looking in past the rear passenger tire on the engine. There is absolutely nothing there on mine. 
       
      1.there seems to be very little info if you Google a 760, or anything Massimo newer than like 2019. 
       
      2. Does anyone have a current model year 760 that can answer my riddle for me?

      2022 Sector 750 EPS starting issues
      By GunnersTacklebox
      Hi All,
      New here, but bought a 2022 Sector 750 brand new last march (old stock up here in Canada)
      It's a good bike so far, but I have noticed a quirk and was wondering if anyone else has had a similar issue?
       
      The issue I've had is if I leave the utv parked on any incline, not even a major incline, and leave it to sit for a while (day or two) it will not start properly. It will turn over and not fire until I press the gas pedal, when it will run and rev up, but if I let off the gas it will die. It will keep doing this until I either start it in gear and drive it for a bit or leave it in neutral and roll it down the hill to flatter ground. where it will have to sit for a while. 
      If I park it on a decline there is no issue. fuel is not low, it's occurred a couple times now. 
       
      Any thoughts on the cause of this? Dealership just says bring it in and let them take a look, at my expense of course.

      2020 Tracker 800 sx front end noise
      By Karlibob
      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      MSU 700 Oil Burning
      By Chile
      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      Which is the best oil to use ?
      By Prepper
      I have been doing a little research on which engine oil is best for UTV engines.  There seems to be some disagreement over using a good quality regular engine oil, and the necessity of using "M2" (or wet clutch suitable) oil.  My understanding is the "wet clutch" suitable oil has less friction reduction properties (hence a more responsive clutch with less slippage).  While less friction reduction properties would seem to be better for the wet clutch... it would not be best for the internal engine parts like camshaft bearings and other moving parts where friction is detrimental and would lead to premature failure.  Some folks swear you need M2 oil, while others say they have been using regular motor oil for years and their clutch is just fine.  Could they both be right ???
      Any thoughts ?
