Recently, I've been experiencing some difficulties. In 3rd and 4th gear, all of a sudden I loose power and when I hit the throttle I go nowhere. The bike still runs, but it sort of bogs down. I'm not sure if it runs on one cylinder or what. One time while this happened I even blew my main 15 amp fuse.
I traced the blown fuse back to my ignition/key switch and replaced. The old key switch was from Lowbrow, which I will never buy again; considering it's only about 2 years old. I replaced with a Honda OEM ignition switch. This cured the blown fuse problem, but I'm still having issues with the bogging down in 3rd and 4th gear. It's not a continuous problem, it more comes and goes.
My first thought was that I might have an air leak or gas isn't getting to my carburetor fast enough. My petcocks are vacuum type and I replaced both of them about a month ago. There is no air leak when I spray carb cleaner around the seals of the manifold.
A mechanic buddy of mine said that I might need to upgrade my points ignition to PAMCO. He said this might help. I'm running a Hugh's Handbuild PMA system. Opinions?
