· My R1 go to warp drive

I use silicone to make sure the rubber around the race bmc filter does not allow any gaps for air to sneak through. My dyno tuner told me to buy the race, from his experience he gets better dyno results so thsts what I went with. I was worried about the filtration also so when I first got it, I inspected the throttle bodies and filtered side of the air box to see if dirt was getting through. The inspection never showed signs that dirt was getting through so I eventually stopped worrying about it.
