Hello all, new to this site, first post. Just got a 2007 1300 R about month ago, Love everything but the sound. Did the Clayton mod to exhaust, deeper sound but difference was minimal. Bought Cobra Slip Ons off craigs list for 100 bucks and switched them out Sunday. I love the sound! My question is bike runs great and i want to keep it that way. I havent adjusted valves, carbs or air flow. I have ridden about 200 miles on new exhaust. Doesnt seem to run any hotter than before, although i havent gone that far yet. I am not mechanically inclined, so if something needs done i would prob take to dealer, and they said with slip ons i shouldnt need to anything- just wanted to check with the group- any reply would be great! Thanks!
