I am a little puzzled. I figured that 15F and 42R on a 2.0 primary was equivalent to 15F and 46 R (as 42*2/1.848 = 45 and a bit). Therefore I planned to set my gearing at 15/46 on a late munster to match running 15/42 on my old SS. Now dropping to 14 on the front would means that my revs would be about 1 - 1.5 K higher ?? I really get what Steve says about the drive and think it will work better for me (personally) through Gerards but dont understand the comparisons.
Puzzled??
