    785cc Hx motor let go.

    So I was riding 40 mph felt the ski start to die but since I was timing the tank of fuel for just normal riding Iwas going to mmake sure it was really low. Two minutes laterit st arted to die and I tried to switch to res erve but didn't fast enough. Well the ski woul n't start from then on and I put a compression gauge on it and had lost it in the rear. Can anyone tell me what it llooks like was the problem from my pictures?

    Low fuel and maybe sucked up a clump of trash in the tank and ran it lean

    Lean burn deto on that cylinder for sure. The Factory exhaust systems do a very good job at scavenging so that is probably why it is especially burnt up right at the exhaust. I would look first for a plugged internal filter on the rear carb. It's been running lean for a little while based upon that damage. Another good reason to inspect spark plugs after every ride. You might have seen the plug color or dryness and inspected it sooner.

    I see tempo fuel lines and signs of green goo. Plugged micro filter.
