primary clutch

[lady bug]

i have a g8 with a torque spring jetted uni air filter exhaust port and polish head cut 30 thousands on a fresh rebuild. i am having an issue getting any top end out of this cart because of the ignition rev limiter. i am only getting about 24 mph but it does have good torque i don't want to go back to a stock spring because i tried that and it just didn't have enough torque for what i do. so i was wondering what you guys thought about the upgraded primary for the g2 thru g22. my friend has one on his cart and that thing does about 31 with minor mods exhaust k&n so i am just wondering if you guys think it will help with my top end with out losing any torque. thanks
