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 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

I'm sure many of you are aware of Michigan's emergency brake requirement. I'm wondering if anyone has a good solution.
Beyond paying the few fab places $$$$.. I'm curious is there another rear caliper with e brake style that would interchange with slight mods to the Maverick sport rear mounting bracket?

Greetings,
I have a client that wants me to install a heater of some sort to aid in cold weather starting (she uses it at her business, has had issues starting the last few days in sub-zero). I would prefer a coolant heater to a pan heater (silicone pad), but I cant for the life of me find the diameter of the coolant hoses. Heck, I'm not even sure if it would work as well in this application given how long the hose is compared to tractors and trucks I have installed them in.
Any advice you could give me would be GREATLY appreciated.

Question, Does anyone know if a 700-cylinder, piston, and head fit on top of a 500-bottom end, Although I have a 500 and have rebuilt the 500 once, I'm thinking the lower end may be the same for both the 500 and the 700. Does anyone have information on that?
