I used nos on my derbi gpr and the back wheel locked up and the engine cut out?

Question

the engine did NOT go bang or make any sound

Answer 1

Nah Na Nah Nah, Hey Hey Hey, Goodbye!

Game over my man. Engine blown.

Answer 2

Dude your engine siezed! Game over!

Answer 3

Ryan's got the right answer. You've seized the pistons!!!!!!  Now it's time to tear it down and rebuild. Your lucky you didn't kill yourself with this experiment, that it didn't happen at a high speed, I mean.

Answer 4

it can still be blown even if the pistons move. way to go dufus!

Answer 5

Your engine is gone.  Sound or not, it's dead.  You added NOs to an unmodified engine, and you obviously don't have a clue how nitrous oxide actually works, do you?  You probably suffered detonation, and I would recommend actual RESEARCH on how & why it happened.

Just because the pistons go up and down doesn't mean your head isn't cracked, your rings aren't vaporized, your plugs aren't destroyed or your valves haven't bent.

Try doing your homework before messing with things you don't understand next time, kid.
