Look up KD cycle in Yuma AZ, I put one on my bike this last month. They fab their own intakes and make them longer than the billet so the air/fuel has more of a straight shot into the motor. The billet intakes are like 2" long so the mixture has two tight turns before reaching the motor, but we all know billet adds 5hp
A bump for taking a beating, I follow this site daily and buy parts from sellers here, the same goes for ebay, but rarely post so i dont have a good rating, doesnt mean im out to rip anyone off. If your not intrested in the sale, move on
