I am by no means an engine guru, but me thinks that you'd get better results by removing the flywheel aka the big magnet on the side of your motor...

It is removed, but the metal shavings aren't stuck to that. With the flywheel being so close to the crank I guess it magnetized it. I never had this issue, this is also my first 2 stroke. Do u think there is a way to demagnetize the crank so I can just flush it completely?

Where are you at in Pittsburgh? Also, you should post this in the "Tech Help" section of the forum so you don't get trolled.

There should not be metal shavings in there, your crank bearings are probably trash.
You need to split the cases and clean / inspect everything. You'll never get 100% of that crap out without disassembly.

You can demagnetize the crank using a tool demagnetizer. Basically it's just an electromagnet connected to alternating current.

Yes I'm in Pittsburgh, I do not know how to use this website lol. The reason I have metal shaving was because I ate 2 pistons in it already, the crank bearings are strong. Good point though, the only issue is that the original owner tried doing some work in it and rounded and stripped out alot of nuts and bolts in there

Will_Frank, meet Dan_R Charles. He joined yesterday and you today. You two should get along just fine under that bridge you share.

if you think the metal shavings are piston mateiral then your crank aint magnitized pistons are aluminum, and yes your splitting the cases like it or not

CW is right, the only way to insure that all the "bad" things are out of there is to disassemble. You state that your crank bearings are strong, but if you've destroyed 2 pistons and have left behind all that debris AFTER you've cleaned it, I can assure you that keeping those crank bearings in there will be a monumental mistake. Take the time and do it right, you'll be much further ahead.

Good point, didn't even think of that.. I kinda knew I had to but was trying to avoid it as much as I could lol. I wonder what it could be from the because all of my bearings are solid. When it ran it, it ran strong and smooth... Tbh I feel like the previous owner got all that shit in there

Probably still munching on stray metal that was never cleaned out properly from the first blow up. When you think it's clean, throw another piston in it, start it up, and you will know soon enough if it's still regurgitating tramp metal from blow ups gone by.

Again, piston ( aluminum) isn't magnetic. Soooooo, if the old rings , wristpin, and wristpin bearings are intact, u need to have a long look at the crank and rod bearing in the big end, as something is supplying u with steel, lol and it isn't your piston I promise

You may want to spin the crank around by hand. My guess is that the problem will be really obvious. Happy case splitting
