Take the exhaust off and have a look through the exhaust port, you will see either a bright sparkly piston or a smeared mess.

I lookt at the piston a few min ago it looks like how a piston is suposed to look like (strangly enough) i tryd to push is down and is went down like normal what i did see is that the piston is dry so my guess is there isnt geting any fuel inside the engin i tryd to start is for 30 min or so

Did you look at the top of the piston or through the exhaust port ?

You need to see the side of the piston.

I would concider a compression test to check if anything nasty has occured.

You might want to look at cleaning the fuel filter in the carb, they get a surprising amount of bits in there after a few years.

Grab come carb cleaner and give the jets a good soaking.

Sounds like you might just have been lucky.

If it has seized i would expect yout little end bearing is shot, that will make the piston start to slap and will wear it out very quickly.

Keep a very close eye on your bike for a few months.

How does it sound? If either the little end or crank bearing has gone it will probably sound much noiser than before.

Whatever caused it, I'd be super careful of how I'd ride it over the next couple of days. Just think of the consequences of that lock up if you'd have been cranked over in a bend at speed!
