Whats up guys, I fired up my roadking the other day and rode about 15 miles to a buddys house. Bike sat for about a hour then I pulled out and was running down the road and got a diffent sound from one of my pipes. I came to a stop and when I pulled off I have a bit of a flat spot/hessitation with a steady popping sound at a little less than a quater throttle in any gear. You can put the throttle above or below that and the sound and hessitation stops. So I just went home and thought, I might have put a low grade gas in "I cant remember". So today I go out and add a bit of octane booster just in case. I fired it up and was getting my gear on and while it was idleing, it made a click noise and the bike idled down real low and made that weired sound through the pipes like it was loading up or choking, then it snaped right out of it and ran fine. I jumped on and road a quater mile and it started making that noise through the pipe with the hessitation in the same spot on the throttle wich is anoying because its kinda my cruise spot at lower speeds. I turned around and went home, stoped and shook the bike back and fourth to make shue the octane booster was mixed up. I got off and let it run for a minute, and you could hear the idle drop like it was going to die along with a different sound comming from the exhaust" not the normal plop-plop-plop harley sound", like I saidd it was like it was loading up or something. The bike did it twice whie it was sitting within about a two minute idle period. It was enuf of a different sound that my wife come out to ask why it sounded different. So some info on my bike, its a 07 police roadking with a 103 motor and 6-speed trans the only motor mods are a set of Vance & Hines longshot true duals. Still has stock breather and all that stuff, no go fast stuff the 103 does good enuf. So what do Yall think, I pointed my finger at it and told it to knock it off but it didnt listen so I need some help. Thanks to everyone in advance!!!!!! Lets getter done so we can ride!!!!!!!
