The one piece Biturbo will work with the Airsail kit, and it works with the stock carburator. With the stock carburator re-jetted, and three 1/4 inch holes drilled in the airbox my bike set up like this goes over 40mph. At the speed of about 45mph with this setup, and a 200lb rider there is still a bit of extra power, it tops out at about 50mph on long level stretches. This is using the stock sprocket. It would go a bit faster with a 27 tooth sprocket.
I am sure that a bike kited with a Raptor kit would out perform my bike. But, if money is an issue, and you want much better performance rather than insane performance, the Airsail kit with a bit of jetting and drilling the airbox is an option.
