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.

This is rocmoc/Michael one of the first on this forum when the Joyner was one of the most active topics. First an update of others. The earlier members will also remember Lenny and Jeff. With myself we organized the first Jamborees in 2009-2012. Sadly if you have not heard we lost both Lenny and Jeff in 2018. A great loss to the community. Myself: Still around but rolled over to Jeep and Arctic Cat Wildcat. The Wildcat design still remains me of my old 2008 Trooper. Doing well as the Last Man Standing but cleaning out the garage. Found some New and used Trooper parts I will list in the parts section. Wanted to give you all a chance before I list on Ebay. As many of you knew Lenny listed a lot of stuff on Ebay. Will I partnered a lot of the stuff with him and I still have stuff. Take care and I will check in for message should you want to ride. Still make it to Utah every other year and am still in Southern AZ.

Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
Thanks Jerr
