Kx85 problem. Answer ASAP

[exrider12]

Today me and my friend were riding in his back yard trails. He was going then his bike stalled. And the kicker wont budge... i was thinking crank bearing. idk just need some opinions.

But 2 days ago he had the carb worked on at a dealership can he bring it back and complain?

Guessing its locked up by the sounds of it. Prolly time for a rebuild, sounds like he got it hot riding in the trailers and locked the piston up. Take the head off and check it out.

Ya thats what i was thinking. He knows nothing about taking it apart... it has a fresh bore to. its a 105...

fried the piston. i used to blow up 80's like bubble gum. gonna need top end gasket set, piston and rings, and a good hone out. lets just hope the cylinder walls are still good though. then it gets expensive...did that once too.
