Bought my M109R about two months ago. I've added all the available Suzuki Chrome and carbon fiber. Just had some custom airbrush paint put on it and the only complaint I have is the throttle control, but read an article and just purchased a JSD-3 timing retard elimiator. Guess I am not the only one with the complaint. Haven't received it yet, but according to at least one other M109R owner, it advances the timing in 1-3 gears to give smoother throttle response off the line. I've attached a couple of pics
