I have been tossing around the idea of gearing down a 2012 PRO RMK 600 with Carl's Cycle 660 kit and Carl's clutching. I'm not concerned at all with top speed. Would like your opinion on this also i'm a little confused on clutching I already have Carl's Clutching kit. Would I need them to redo my clutching if I gear down? I would like to hear from anyone else with an opinion on this also and remember this is a chain case sled so the cost will be reasonable
