It was really windy out on that second ride, so hard to tell if it was better or same, other than smoother and sound. How would you know if the top end is too lean, backfires? It still pops when decelerating.
I see two K&N filter kits. One with one big filter and one with 4. Which is better?
The 4 individual pod filters are for a stg 7 set-up.
