Can you try to free up the piston from the jug? Because we need to figure out what happened and go from there.

Try spraying pb blaster in the spark plug hole and let it soak for a bit. Then just a little turn to free it from the cylinder wall. Then check your timing. It could be binding up in the valves and not letting it turn.

Or just take the jug off and let’s start inspecting parts to again, see what happened

I’ve blown pistons and luckily was able to figure out what happened. Could be simple, could be time for more. But we will figure it all out together.

We are all quadcrazy.

@06kfx440 has some great points. Hopefully an easy repair. If not, start looking on ebay and craigslist. You can also try used atv parts houses like powersports nation.

I did get the piston to move but I have very little compression now do you think I should take the jug off

thanks

Yes. Low compression equals bad rings. Or cracked piston. But pull it off and inspect the jug liner and hash marks

You should inspect the crank while your in there. Check connecting rod bearings and maybe inspect the timing chain and or tensioner.

Did it seize or just lose compression?

It seized unfortunately

Time to rebuild. Pull the engine out and work on a bench so you don’t lose anything.

I think I better get started

carefully take everything out and see what needs to be replaced?

Pictures and videos are key

In would start by pulling the cylinder off of the engine and then the piston out.  Take a good look and see if you can find where the failure happened. Maybe the wrist pin clip came out, the rings maybe went etc. As @06kfx440 stated check the main crank shaft for any play.  If all else checks out on then your good to go.

If it’s just the cylinder head and piston then try to locate a new or used on on eBay.   If you find a good used cylinder head then spend the money and put a new piston in as well.  Makes sense to do this since your going through the effort. Make sure your oil pump is working properly and that the oil is getting to the head and lube all areas up good prior to start up. 

My guess is it was prob a failure of some sort with regard to the piston and the wrist pin clips or rings.

That was my thought too frank. You can tell what happened by pulling the jug off.
