I have heard a couple different choices for gearing. Stay with stock front size and go up 2 in the rear, drop 1 in the front and stay stock in the rear or drop 1 in the front and go up 2 in the rear. All while going to a 520 convertion. Any ideas on whats the best or any recomendations? I have a 2000 R6 that has a full Yoshimura system, Ivans Jets and Factory Pro velocity stacks. Thanks for any info.
