Love the bike. I have an 08 C109RT that is a blast to ride. Its similar to the M but with a defined engine and of course more of a cruiser than sport. Are the air filters that mesh type? If so they don't filter very well. Had Edelbrocks version on a Chevy small blockand I found a lot of dust inside the assembly and I know it was properly installed. I hope this version uses a much better filter media.heres my beast. 06 M109R. 1800cc's im out of here.
