That would be about a 15/43, which is just -1 from stock. Actually I've got a 520 44 tooth rear lying around. So maybe I'll just order 15/43 kit and play around with the 2 rear sprockets and see which I like better.
if its true that is sad, we lost our last one years ago. Hope the same doesn't happen to NJ. And then they will bitch about street racing when they are the same people who got all the tracks closed down.
