Busted valve

I justed replaced my motor with a used motor that is stock except a muzzy turbo i installed.I started bike it ran rough so i had to rev it to keep it running so i could adjust the idle after a few minutes it died and would not turn over.
I took the valve cover off and found a busted tappet on the #1 piston exhaust valve.
So thats no problem i got a extra complete head but after pulling head i find the valve broke in half and stuck in the piston,also found a bolt in there to.
I recieved the motor with out throttle bodes and has not missing any bolts when installing motor.
The cylinder wall is fine and i have 4 good stock pistons would it be ok to just replace that one are do i need to do more S7300200.jpg

That bolt is what ruined your engine.
If I were you I´d change the connecting rod as well. It probably got stressed when the piston locked.
