Default Porting question.....please help


I have a pretty modded out banshee that was originally set up for sand drags and hill shooting. It does not have crazy power but dyno's out in the low to mid 70 HP range. The top end power is awesome but the low end really really stinks. Short of rebuilding the motor is there anything I can do to get some of the low and mid range back???

Thanks!!

The ideal thing to do is go with a lower gear ratio and a taller tire. The lowend will be greatly better and you will not lose any top end because of the tire rollout. Changing to a 17 or 18cc dome will also gain some bottom end.
