I finally got to run my bike with the new Spark Cam installed. MAN what a difference. This thing makes soo much power now!! I love it!! it really really makes the bike feel strong, it pulls right to the rev limiter and beyond!!!I am very impressed with the power it makes now with the Sparks cam!! The power increase was from the very bottom to the very top. The only jetting change i made was turn out my air screw 1/2 a turn more.
