It's hard to say what exactly happened till you get in there. I would buy a manual and do the top end myself, it's extremely easy on a two-smoke, even more so if it was air cooled. When you do get the cylinder off, you may be able to read of the top of the piston what size bore you are on now. Never get anything bored without having the piston that is going into it miked (micrometer) first. If you know what piston/bore size you need to go to (I reccomend wiseco pro-lite) order it then take your jug and piston to a good shop and they'll know what to do.
Another thing to do while the jug is off is to check the play on your main bearings, and inspect the cranckcase for anything out of the ordinary, a manual will greatly help with this. You can even get a cd-rom manual off e-bay and other places, and it's only like 5 bucks. Good luck with whatever you decide to do.

There is a bike shop by the dunes where i was, and the machanic told me to take the spark plug and and try to kick it over, it still wouldn't budge. and there was some tiny aluminum pieces on the spark plug, he said it was probably my piston or piston rings. i also mention that the guy who worked on my bike before said the counter balance was getting worn out, so i guess i wont know for sure until i can find a place and time to tear into it...

You guys think i could find a new rebuild top end for about the same price of getting it fixed, like off of ebay, or maybe craigslist?

Im only a certified technition and have been building engines for the last 20 years since I was 10....... so if your so good at it why is it were acting as if his engine was a FOUR STROKE?????????????????? and I think what you mean to say is you can UPGRADE the carb and ignition system as it was already designed by the MANUFACTURER.......with all due respect, please do not try to get into a pissing contest with me as you will LOSE.

Building a 2 stroke engine is a bit more tedious than building a four stroke engine. The internal tolerances have to be just about perfect or you will have major problems. Remember a 2 stroke dosnt have crankcase oil to lubricate the piston crank and rod. They use the oil from the Fuel/Oil mix fuel you run.
What probably happened is that the forged piston expanded from heat and bound up in the bore. Get specs from Wiesco directly for piston to wall clearances. Allso ask about RACE applications in which case can require more piston to wall clearance.
After a bore job if you assemble the topend be sure to clean the jug with soap and water then lube it with either pre assembly lube or 10W30 oil. Allso be sure to measure both your bore and piston to be sure on proper sizing!
