I installed mine this weekend. It sounds louder, but i have not ridden it due to it raining. I will take it out tonight if the weather holds.
Picked this up on the Wing BoardKenCrawleySC said:My mileage is now 15,600. So I have 3,400 miles on the K&N Filter Mod. A high speed run from SC to DC and Back, and some backwoods hauling around, plus the 100 mile/day commute to work all show that the modification is a good thing. The best feature continues to be the low rpm getting started when cold is no longer lurching and chugging. The response of the throttle is smoother. Intake noise is very satisfying when passing on the interstate. I think the noise also repels sex-starved deer from Hwy 78 at night. Or is it my lights?
Someone needs to dyno an unmodified Rune and post it under this subject string.
