I have a 07 roadking with a 103, ran fine with no problems. Installed a gen3 dobek programmer and went for a ride. After about 30 miles I started to hear a "CHH-CHH-CHH-CHH" sound running in sync with the rear cylinder exhaughst, and a small pop when you are accelerating- but runs ok if you run alittle over speed limit. When I got it home and inspected the bike I used a stethiscope and found that the chh-chh-chh noise was comming from the rear cylinder crome pan that is on top of the jug. Its like its leaking air from the rear part of it, ther are no motor noise just a air sounding leak that smells like exhaust. Can anyone help me with what this would be? I know the valves are under that pan but like I said, I dont have any motor noise and the bike isnt running bad-misses-stalls, just a small,quiet pop on the roll of the throttle. So what could be leaking exhaust fumes from that rocker pan, I thought it would leak oil. I need help, I have been run up a tree with this bike and could use some good advice and knoldge. THANKS TO ALL!!!!
