Before you do anything else can you tell me exactly what you are experiencing again, please.
ROFL
Yes, I was pretty terrified because the scooter would not accelerate much and the clutch would continue to slip from lack of torque, but on the nitrous it kicked the front wheel up a bit and the clutch gripped to allow full RPM acceleration. Once I realized that I was going faster than expected on such a short road with the end approaching ever so quickly, I let off the gas and the engine cut out and I was able to hard brake enough to avoid a catastrophe!
Anyway prior to this almost incident, I had tuned the carb to its best on some fresh petrol and I static tested the nitrous on it. Now the carb was set optimally on the low speed so that it would sharply accelerate, any richer caused a further delay in rev up and any leaner caused the hollow-sounding hesitation indicating too lean. When I tested the nitrous on optimum low speed setting, the engine revved up as normal yet once I released the gas the engine almost died but I was able to save it by opening the throttle and passing that bog through, then it would continue to run as normal. I then richened the low speed some and the engine would stall out with the same test despite trying to pass the bog through by actuating the throttle. On the lean setting, the engine accelerated but would idle almost normally without much bog at all.
Also when I test the system with the air cleaner off and the two pipes are exposed, I put my finger close to the two nozzles and I can tell that there is a significant lag between the nitrous and the butane. Now, both of them seem to discharge simultaneously, except the nitrous empties itself out of the longer pipework much faster than the butane because the liquid butane continues to flow about .75 to 1 full second after the nitrous has emptied its pipe. And along with my carb adjustments, this leads me to believe that the fuel lag is killing my engine when I let off the nitrous button.
I hope that explains what I'm experiencing.
