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.

I have an Axis 500 4x4 UTV that I was given. It looks like an almost new machine with 39 hrs on it however it was apparently under water from the hurricane . I have no spark at the plug. I have replaced the plug, the plug wire, & the stator so far. Can anyone advise me of what i need to check and or replace to get this thing running? Any advise would be greatly appreciated.
Thank You,
D Maynard

Just wondering if mine is the only one that’s seems very loud while driving. It just seems louder that other brands I’m use to. I guess you get what you pay for I’m assuming.

Hello All...
Just bought a 2014 Massimo 500 UTV. It;s not running at the moment, but hopefully will soon. I need a seat for it also (passenger side, if it makes any difference.) It is a crank-but no start situation. Just now starting to read the boards for solutions. Apparently these models are well known for this issue. If anyone has any suggestions, please feel free to chime in, it would be greatly appreciated.
Thanks

I am considering a Hisun 550 for tooling around the farm> I have a Kawasaki Teryx 4 and deeply disappointed at the difficulty of getting to the engine and belt for repairs. I would like some feedback on the Hisun's reliability and ease of access to work on. Thanks.
