Is there a command module that will allow you to retard the timing for that bike on the market? I didn’t know there was. Course I been out of the loop for a couple years but all the nitrous I messed with was neccessary to retard the timing or at least stop it from advancing too far.The older models had mechaical advances so we just used a pin for track day. If not, theres some burned pistons waiting to happen.
I would say stick a turbo on it but the compression is too high for anything more than 10 or 12 psi.

..nah, this turbo bussa was running 4.90 in the eighth. I ain’t saying your ZX12 is not a mean bitch. Just saying, the amount of NO2 to make it go that fast would blow it the hell up.

I've never looked into it, but I'd be surprised if there wasn't a Power Commander Module that pretty much gives you complete control of the injection and timing.
