Any one know if it picks up the power adding a K&N air filter to a stock maped bike with a slip on ???If it does'nt help I prefer to stay with OE.Just curious on my 2000 that I bought used & while swapping the fuel tank checked it for the first time & it is dirty.Just was curious because on my Busa fuel map I used it made more power with the stock filter.Also was looking at disconnecting the vacumm diahphram to the top of the air box so it would stay open & remove the snorkle to improve air flow.Thanks for the input!! ;D CP
