good increase to throttle response great with the addition of a pipe and jet kit.

Makes adjusting the fuel mixture easy and quick. I highly suggest getting one if you put a Jet kit in. Also works on Raptor 350

I bought the boost bottle about 2 months after getting my banshee. Hoping to add a little acceleration to the banshee I spent about an hour trying to jam it in place without taking off the gas tank and all the front fenders. I found out it wasn't going to fit. So i spent another 30 minutes taking off the front fenders and gas tank. Once i got the boost bottle on i noticed the gas line looked kinked so i tried running it to see if it was kinked. It wasn't. The boost bottle had a very tight fit. I kept the bottle on there for about 3 months untill it got so hot from vibrating on the cylinder head it burn't a hole in the gas line. SAVE YOUR MONEY AND BUY SOMETHING WORTH THE MONEY DON'T WASTE IT ON SOMETHING THATS GOING TO ADD MAINTANANCE.

I bought this to help with a starting issue on my CRF250R Honda. The adjustable leak jet feature is really good. The Acc. pump block really did not live up to my expectations and I still had hot starting issues.

The snap was super easy to install on my '12 250 SX-F and it definitely added low end torque and quicker throttle response. I ride my bike on the trails and was looking for more bottom end. I don't ride much on the top end so can't comment on performance at that end of the power range. Didn't want to spend the bucks but am glad I did. Good bang for the buck in my opinion.

Installed on a 2010 CRF250R, used the short velocity stack (for improved mid to top). I noticed a slight increace in torque, improved throttle response and slightly more top end. Air4orce definitely made a noticeble improvement over stock.
