OK, so some will correct me if I am wrong..... I encourage them to do so....... My previous busa was a Gen 1......(i miss that bike). It had 33000 miles on it. I added a small shot, a 40shot of dry nitrous to the bike, had a nitrous express solenoid with a 30jet. It was an easy choice for me....... I didn't want to go too wild, I didn't want to race at the track, it was my daily. I just wanted to hand out beatings to newer bikes from time to time. U know? Teach them a lesson launching from a traffic light. And it was cheap compared to going turbo. And lessons were taught. Mine was a sneaky Pete system, so I kept em guessing...... And I kept gassing...... For over a year with no problems. I only used it when I needed it. I had more plans for the bike, but then 3rd world traffic happened...... But it was not nitrous that killed the poor thing, it was fuel, as Mr Brown and a few other org members pointed out. I'd say, if was just for some happy giggles, go with a small shot af nitrous. Just be sure to data log to see what the motor is doing, and if you decide to go a little bigger....... Reinforce that motor with some tough bolts....... Otherwise, you'll be OK.
