The mudbuster cam is exactly that, I just put one in my 06 suzuki vinson500 talk about waking it up! I race a little at budds creek and do a lot of wheelin in the hills of southwest VA and needed a lot more low to midrange power and man did I get it. I had to change the stock rear axel to a sport one cuz the increase in power and my 28 in. mudwiser tires snapped the stock one. I feel sorry now for anyone beside or behind me in a mudhole or a good hillclimb.
