I sent ya a PM Snakes. What is your chain size now? I know the 636 came stock 520 but I geared mine anyways with a +2 rear. If you gear it, I recommend getting a "speedo healer". They are only like $100 but it can be programmed to correct your speedo back after changing the gearing on your bike. I set mine up so that it read the same factory speedo calibrated error so that I'd have accurate milage.
