I changed the front belt sprocket on my 2000 Nightrain to 34T (Was 32T), for less Hi-way RPM. I also installed a new (Stock replacement) 1-1/8" drive belt & still have a 70 Tooth rear sprocket. Problem: Sometimes when riding 2-up my belt skims the starter Jackshaft. Fix: Install a 66 Tooth wheel sprocket to lower height of belt But... I can't find a 66 tooth rear sprocket that uses a 1-1/8" (1.125) belt! Anyone know of an application I can refer to so I can purchase a 66 Tooth sprocket to fit my 1-1/8" belt?
