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.

I'm working with a 2015 MSU-500. Basic symptoms are it cranks well, but will not fire. It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference). It has compression. I bought it not running, and no other information was available. It has 775 miles on it and 127 hours. It looks to be in very good shape. Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
My questions relate to cam/valve timing, considering the symptoms and diagnostics so far. My thinking was the woodruff key sheared off and the crank spun, making it out of time. My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct? In the crankshaft picture you can see a timing mark visible. In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another). However, the long arrow in what appears to be bolt configuration in line with the piston/rod line. Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust. I think it's at TDC, given the visible crank timing mark and valve lash on both valves.
Any thoughts ? Does this appear to be in proper valve time ? Have I missed anything simple ? Thanks in advance for your input.

Hi everyone. I am new here to the forum and am excited to learn from all of you with more experience than me with UTVs. Our Axis750 we use on the hobby farm started to have some issues going into gear. Yes, foot is on the brake and completely stopped as required with these machines. I thought it was the linkage and adjusted it to where it is accurately shifting with the engine off and key in the on position. I start the engine and it won't shift gears (yes foot is on the brake). I thought maybe it was the shift lever teeth so I opened the assembly and this picture shows what I just found. I assume this means the wet clutch would need replaced too while draining and flushing the oil. What else should I consider or be looking at? Any idea what could cause this? I don't see visible leaks or cracks in the system anywhere. Thanks in advance for the help!

2010 Hisun 500 - Carbed'. She sat for about 3 weeks since last use. Couldn't get it started.... has spark but plug was not wet. Bought new plug, cleaned the carb, confirmed fuel pump (pulse type) is working. Still nothing. Put gas in the plug hole.... started right up and idled as normal and drove perfect. Used it for the rest of the day without issue. Tried to start again next morning.... same problem. Poured gas in plug hole again.... started up and best kind again.
Anyone have any insight to what's going on?
