Hello, just really getting into the old "way of the blade" I own a 929 and luv it, much better than my old Marlboro Yam T-cat! Anyway Ive just bought a set of sprockets 15tooth front and 44tooth stealth rear and was wondering what chain to get? I know it should be standard length with 530 pitch but what is the standard length...108?? Also will this screw up my speedo readout, if after the sprocket upgrade my speedo reads say 40mph what will I really be doing? Cheers in advance! Safe ridin'
