The 96 sport 400 is still holding up to the NOS system. I have a friend that has HPD's full race setup on his 400 Sport. And I can beat him in a hill race with a 170 LB person on the back of my quad(riding dubble). The bike has not shown any Signs of braking. Power at the touch of a button.The rush is a great feeling. I have run about 100 LBS threw the motor.Most of the time I ride my wife on the back of my quad.SHE LOVES THE RUSH!

 

Are you using an electric fuel pump for the gasoline side of the nitrous system?
How large a bottle are you using? Where is it mounted? Is the system a Nitrous Oxide Systems unit?

 

Yes it is a nitrus oxide system. And yes it uses a fuel pump mounted under the seat with a 21/4 bottle mounted next to it.

 

Where did you buy the kit? How much you paid for it? Is it a must a second gasoline tank?
