Couple of questions for those who've been there / done that. I'm doing some long term planning for a revamp on my bike and was considering a slightly higher final drive ratio in order to save a bit of gas and maybe get a little more speed. I was wondering if the later Monolever final drives have the same spline as the earlier G/S and ST final drives. Also, will a later GS 4 lug wheel mount up to the monolever 4 lug final drives? I'm betting StephenB can shed some light here.
