From my experience with nitrous, nitrous is bad stuff for 2 cycle motors. Maybe I was injection too much in even though I was using the smallest injector in the kit. The motors I blew up couldn't handle the the nitrous. I blew out a couple of expensive reed cages ($150 ea.) and one time one of my piston top crumbled. I used it on a couple of C1 motors and once on my BZM (which is a $1200+ motor.)
It's a kick in the pants the second you press the button
then it a kick in the wallet once the motor dies.
