You kept telling us the parts were a month old and compression was good.
Most of us here sorta knew what was wrong when you ran the engine without the cooling shrouds. We tried steering you in the right direction.
Nice to see ya are finally coming around. Hopefully you might get away with just having to replace the piston and rings. Will depend how scored(damage)the cylinder is.

Sorry to hear that man. Hopefully, as GSX stated above, it didn't tear up everything. I would sure never go back to the fellows that did your engine work.

Can stator be the reason why compression is low? They came n got it for free he told me the mechanic said it could be the stator

But whatever it is they need to fix it also I was using full synthetic 5 w 30. Another mechanic told me that was why. I should have used 20 w 40 because it's a air cooled engine

Can stator be the reason why compression is low? They came n got it for free he told me the mechanic said it could be the stator The stator has nothing whatever to do with compression. Compression is affected by the rings sealing against the bore, the condition of the bore, (out of round, gouges, scratches, etc) valves sealing against the seats AND opening and closing at the correct time, valve guides and seals, and the head gasket and sealing/mating surfaces of the head and the cylinder. Oh, and the spark plug must be sealed properly with it's gasket as well.
I think that is about it...I may have missed something but ANY mechanic at ALL SHOULD know that the stator, which is an electrical component, has nothing to do with compression. These are the same guys that left off your shrouds, and left bolts off and loose. Man, I would not let them touch anything of mine...ever.

Everything this guy said is true. You fried your engine running it w/o the shrouds. Ant the stator has 0 to do with compression. the oil thing? Well for the short time that you had it not much chance of a lot happening with that. Lots of people run just fine with the oil you used.

Excuse me the firsy guys did the loose bolts n bad work. The second did 100 bbk . Picked it up today n mechanic said stator. I felt like he didn't want to admit that it had something to do with the engine . Although after psi 50 . We all jnow the culprit. So they picked it up for free. The dealers seem to know a general knowledge of scooters. Just going off mechanics word

Piston rings move all except middle. He said he is going to change piston also exhaust valve is leaking

I felt like he didn't want to admit that it had something to do with the engine . Although after psi 50 . We all jnow the culprit. So they picked it up for free. The dealers seem to know a general knowledge of scooters. Just going off mechanics word No excuse needed. 2 people worked on your scooter, seem both of them screwed it up. You came here looking for help and a lot of us here tried helping. You still wanted to trust the ones that worked on your scooter and the bottom line was when they worked on it, it did not RUN. One mechanic said you didn't need the cooling shrouds, the rest of here did. So you believed one person vs the many that said you did need them. ¯\_(ツ)_/¯ Bottom line, your engine got cooked/damaged. No cooling shrouds = overheating. Going to guess that the carb was never up jetted when the BBK was installed = running lean = overheating(plus no shrouds). Then you had a cone filter installed. They have less air restriction than the stock air box which also causes a lean condition. You needed to up jet again. Now you were running leaner then before = more overheating. I am actually supprised there isn't more damage. ¯\_(ツ)_/¯ Now you were trying to start a toasted engine. Crankning/starting the hell out it and douching it with starter fluid(in my opinion not healthy for any engine)and burned up a starter and or drainded the battery to nothing. Then you jumped it with a car and now have possibility did some damage to the starting/charging system seeing the amperage from a the charging system was 10 times more then the scooters. ¯\_(ツ)_/¯ Well anyways, nice to hear you are finally getting things sorted out. Hopefully some of our advice here was helpful.

I would of had the whole head replaced. With all that heat, that head has to be warped. I dont like the looks of the cam shaft bearing cradles. Almost lookes like the bearing spun or the bearing caps were loose and things moved around some.
