I'm Jeff new to the forum, hi to all, I have 1995 FLSTN, heads done, S&S super E, V&H exhaust with crossover. I will try to describe my problem and appreciate any help I can get. I have had the bike for ten years. When riding two up and pulling up a hill there is the feeling of a hesitation under 1/4 throttle, like a slight bucking, like I'm tapping the brake. It goes away when applying more throttle. It's not rythmic but more random. I don't hear a misfire, and the bike seems to vibrate a little more than it used to. The primary chain is adjusted correctly, new plugs installed. Could this be a compensator issue and how do I check it? Thanks in advance.
