Hi there, I have an 07 kingpin. I had installed the lloydz timing wheel at +4. Bike pulled very well, but it feels "thumpy". It's not like a vibration but like the explosion is making the bike shake. The idle seems kinda lopey also, and if I barely twist the throttle it sort of stumbles until about 2k. Then it's fine. The plugs actually look a little rich and it had been dynoed before the wheel. I'm not sure if I should add fuel at and around idle or what. I retarded to +2, the feeling of vibes were better, bike didn't respondas well as the 4. I want to go back to the 4. Anybody have tthis happen? I've searched alot and found little advice. Yes the torque of all bolts were checked, checked and re-checked. Suggestions would help.
