I have to disagree with our bud from Canada. When you install a free flowing exhaust, you normally should jet the bike to pass more fuel to take advantage of the increased air flow. A K&N filter will let more air in, and the exhaust will let it come out. Without rejetting, the gains will be less....and I mean jetting up, not down, as suggested by our Canadian friend. Normally, a free flowing exhaust has some unwanted affects on low rpm torque, such as the symptom you described above....my F2 does it at light cruising speeds...Mine has a K&N filter, a Vance & Hines full exhaust (SR2 I think...4?) and a jet kit. I bought the bike that way, so I don't know how exactly it was affected-runs good though!
Try a jet kit and filter, and you should be satisfied. Take care and have FUN!
To ride or not to ride? What a stupid question!
