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.

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 have a 2016 550, ive tryed the hisun website and seems i cant get parts there. I would like to add power steering, have seen a few "kits" on ebay
for the 750 not sure if its the same parts needed for the 550, there is a factory bracket already welded to the frame above the standard steering rack, is this to be used
to mount the eps motor? There is also a grey plug hanging just above the brake master cylinder, not sure if thats anything that needs to be used in the install.
Handy with wrenches so if i can find the parts installing it shouldnt be a problem, anyone done this upgrade, was it worth it?

I have a Coleman HS400UTV-5 got it manly for hunting and spending time with the grandkids
The one problem I am trying to avoid. My son borrowed it last summer and said it ran hot so he added water to it . I do not know how much he put in so I would like to drain most of it and add new coolant to protect it this winter. I can find no drain cock or any way of draining it besides loosening a hose. Any suggestions ????
