70cc Giannelli Shot?

[BEN-AEROX]

Hi, I have the TP Due+ kit and i have a giannelli NRX pipe... Today i got clocked at 60-65mph but i no it can run better on the Shot pipe. How much more speed/power am i looking at gaining by fitting a shot?? SIP-scootershop say that the Due+ maxes out at 75mph with the right exhaust (nardo/shot) and its an estimated 14bhp. Aparently the NRX is similar to the Shot, but the Shot works perfect with the Due+... so im told im probly loosing power by using the NRX, maybe 2-3bhp, and some MPH, which i dont want to do !

Aloha, I understand the shot is higher revving pipe, so you may need to raise your ports a bit.. Also I think a true 75mph from 14hp is a bit optimistic, maybe a true 70mph, unless downhill a bit and the wind at your back.
