Alright...I am going to be replacing my sprockets and chain w/in the near future. I wanted to get some suggestions on the gearing. Stock for my bike is 15/43. I have heard that -1/+2 usually works well. Also, I have heard conflicting stories on whether changing the gearing will affect the speedo or not. The guys at TFOG say that the F2 reads off the front wheel so it doesn't matter. I have also heard that changing the gearing would affect fuel economy and possibly more vibration in the pegs... . So, any suggestions would be helpful!
