uh oh!wtf happened?

Ok heres the latest on the motor...

Its tore up piston is fried and definately needs rebored.the cylinders scarred up and the piston melted to the cylinder wall is why is stuck.

Which is awesome considering i got 4 hrs on it.

My jetting is 340 main and whatever vitos sends for the pilot and since it ran retardedly rich ken suggested putting the stock jet needle in it on the very bottom clip and it ran like a dream now all of a sudden outta no where it just locks up?wtf im thinking about a yfz 450 or something less finicky idk im pissed off!


So how much am i looking to go up on the bore one size and a piston?ken you got any specials right now?lol seriously though how much?
 
It'll be about 120 for the piston kit, wiseco that is, and a bore job is roughly 60 bucks. You'll have to have the bore measured to find out what size piston to get. edit: oh shoot i didnt notice you had a bbk, scratch that ^
