On top of seeing a little gap between the head and gasket, you can see oil residue in that area. I'd be pulling the head off at least anyway knowing it was ran without a fan and shroud. That's hard on these engines.
It looks like a minarelli engine, but I've never seen one with a CVT cover like that where the clutch portion sticks out so much. I wonder if there's anything different under there?
That residue in the pic is actually whats left of the shroud. It is melted all over the head also.
I took the head and cylinder off and was suprised there wasn't more carnage in side. There was some scoring on the piston, but the cylinder looks good other than the plastic melted on it and I've gotten most of that off. A few mins. in the sand blaster should take care of the rest
Not too sure of the make of the scoot but the body is the same as the Rocketa MC17 and it has this plate on it
Nothing odd under the cvt cover
Ive got the chassis cleaned up and ready for the new JOG90 that should be here Tuesday.

Cory and I spent the day cleaning the garage and working on scooters. Here are some pics of what we found under the flat black, after we spent a couple of hours with lacquer thinner on some of the body panels
It needs some body work so I'll have to paint it. I was kinda diggin the color till Cory said it looked like a chick's color :lol:

With a piston and ring looking like that I can just about guarantee that the cylinder looks equally as bad. You should have in honed to say the least. I would also be looking at the connecting rod bearing and pin. I have worked on a lot of 2 stroke bikes and when ever that came out of a cylinder you knew that at the least a honing was in order. What do the reeds look like are they warped or bent. There is no way with that kind of heat that nothing else go damaged. What does the fan look like is it missing fins or does it have junk in it, this could be the reason for it heating like that. That looks like self detonation like a bomb went off. You got your work cut out for you, keep us posted.
Here is a trick for you to learn. If the head gasket is a copper gasket dont throw it away, you can re-use it. What you say. Take a propane torch and heat the gasket up till it is cherry red and then dip it in anti-freeze, this will soften the gasket back to being pliable again. If it has a crack or rip in it throw it away. Copper doesnt go bad.
