I was checking these spike air filter set-ups out, and had thought about buying one. I'm no mechanic by any means, on bikes anyway.....Are these more of just a cosmetic item than a performance item, and do they require any adjustments as far as the motor?? If it helps any, I have HK Sideburners, and did have it jetted when they were installed.....Thanks in advance for any help!!
