It is a universal kit from www.mpsracing.com cost me about $400 w\bottle
it wires into the horn and there is a switch to swap from horn to spray
that would suck if i went to toot my horn and accidentaly sprayed
ohh and i live in mississippi

 

that sounds allmost like the same kit i put on my buddys bike. wired it to the horn button and everything. ohh the good times ! we would push the button in third or 4th gear. got to shift fast though as the rpm,s come fast as hell.

 

You can install a activation swicth like evil said so you can turn the power of at the solinoids and no matter how many times you hit the horn it wont spray till ya flip the switch. Or hook it up to the powercomader or rpm switch and select a certin rpm to activate it, I would feel safer this way that way you can hold on better instead of hitting the horn botton. Instructions are pretty explainitory you should have no problem installing it, just do some research and see what is the best shot for ya bike, me personally would stay between 28- 40hp shot nothing over. Also do a parts check b4 you start I've gotten a few kits both nos and nx that had missing items, and it sux to have everything torn apart to have to put it back to stock till ya get the right parts or missing parts. anyways good luck and enjoy it will be a blast.....

 

i understand that you can have it setup to activate at a certain RPM.
lets just say i want it to spray in 4th gear at 10k and have it cut of before
the rev limiter kicks in, is that possible? and if i did have the system setup to spray
10k rpms how would i keep it from spraying in `1st,2nd,and3rd i do not wish to
activate nitrous in these gears or i may end up on my back with the bike on me.
also how would i controll all this with the power commander? have you done that before?
did you have any professional help? or was i t some tinkering ya did on your own free time?

The bottom of the page talks about the rpm switch and gives part numbers as well, I think this is the sams company you got yours from if anything give them a call let them know you purchased thier kit and they should be very helpfull in pointing you in the right direction.

 

me personally i wouldnt do the activation switch because say you forget its on, want to romp it a few times on the freeway and blam, insta romp because the juice kicks in. at least with a button, you can hit it when you want, also turn the system on or off like mac mentioned. im not certain who makes it but it looks like a L bracket that you mount your on off toggle and a activate button and it bolts onto the throttle side clip on. when you roll the throttle full, your thumb taps the button. kinda cool and you know when to hold on.
