I couldn't find anything on google or other websites....

 

 Pretty sure the camshaft will have a automatic compression relief on it that relieves compression out of the cylinder via one of the valves during start up, so usually when cranking the engine with a compression tester the reading won't be the Exact compression of a engine running at 2500 RPM, But, it seems to be  a baseline for all  small engines whether it be lawnmowers or 4 wheelers,  seems as though 85 to 90 PSI is the minimum to start a 4 stroke engine.

      Is the cam sprocket a bolt removal or is it pressed on? Dang bolt is on tight. Impact wrench won't even move it.

      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.
