Setup: SE Intake / Doebeck Gizmo / RC Comp Pipes (Stage 1) Hi everyone, Took the new toy out today for its second ride. The bike is new and so far I have had barely 20km on it. As soon as I merged onto highway and started to pick up speed, I started to feel a vibration. I felt it through the handlebars, but it felt like it was coming from the engine. Within the city at usual low speeds there is nothing. I was in 5th doing almost 100km (55mph) and the vibration was very evident. I downshifted to 4th and as soon as rpms went up, vibration dropped significantly. I gave it more gas in 4th, and then back to 5th and juiced it up again. Its not the wheels/tires as when I engage the clutch at these speeds, there is zero vibration. Any thoughts you may have would be greatly appreciated. I even thought that maybe I should switch around the plugs that lead to the injectors from the Doebeck unit.. But that shouldnt be any cause. I just have no clues as to what may be causing it. Its not a full shake by the way.. A vibration that feels like an engine not working well combined with wheels that ar not balanced.. That type of thing. Thanks for your time.
