 Our Big Air Kit vs.  stock carb and airbox

We designed the kit and even coined the name "Big Air Kit"

For the V Star in 1998 - maybe before anybody else had even entertained a thought of removing a cruiser's airbox for more power! It seems that the name has become the favorite term of some others! Go figure!
We took our years of experience in tuning non-airboxed bikes, worked through many setups - testing on the high quality Low Inertia EC997 Eddy Current . This allowed us to make many small .1hp and .2hp changes that eventually added up to a massive 10% to 12% power increase between 3k and 5k and a healthy 8% to 10% increase to peak True HP numbers. All that with absolutely no loss of low-end and cruise power. No slide drilling is required.
Mileage, when properly tuned, doesn't seem to suffer appreciably, according to feedback from customers.
Full Big Air Kit includes: individual K&N or BMC washable air filters and a custom, matching Factory Pro Carb Recal Kit (item contents similar in quantity to the above 1.0 kit) for jetting ease. 
Note: If using large diameter, non baffled exhaust systems, it is usual to use larger than stock pilot jets. We can supply these at additional expense if requested.
