That is a load of ****... NO ONE can come to a conclusion like that with so many variables to take into consideration. What about air density/temperature, your particular air flow/intake, every motor is made dif and do not perform the same. Why raise the needle - because you need more fuel

Death is right, anyway if you dont put more fuel to it, power gains will be next to none because your not feeding it any more fuel to burn.
Not trying to steal your forum xkingraptor350x just a similar question though. Hey guys, I have a fmf powermax or something on the quad i bought used. The guy said nothing bout rejetting but told me of all the other things he put on. Do I need to rejet if he didnt. Thanks

We cant answer jetting questions as a black and white yes or no. You may have to or you may not have to... The only way to tell really is to get out and ride her - start reading those spark plugs!! A plug reading will give you a better answer then any of us on here could.
