I was looking on e-bay the other night and ran across K&N's for a RSTD. The numbers were different than the RSV and like $30 bucks less. I thought basicly they were the same bike except the fairing-gas tank-speedo deal. Looking @ K&N site they show the YA 1399 for both the TD and Venture. Maybe they had the years mixed up or something? Does anyone else make a filter for the RSV thats worth running? Unipro anyone run them?
