Just purchased this bike a week ago. Did the break in that the dealer recomended. Change filters and oil and took off to the river to ride this weekend. I am experiencing a lack of lowend power. Seems to hit the sweet spot half way in the throttle in second gear. Notice the sprocket is a 45. What suggestions to you have on beefing up the lowend? Not planning on doing a whole lot of street riding, maybe should have gone with the SX-F? But didnĀ“t so how do I fix it?
