I ride with 3 other banshees.. They all have some engine work but this one banshee has so much torque down low and mid range.. I can beat him up top in 5th and 6th but hell get me in the mid.. I think he has cpi pipes, 18cc domes, milled head, larger carbs ported and polished.. I think its a stock bore. My rear tires may have something to fo with it also. The tread on them is sooo low!! Need new ones asap. He has brand new razors.
