Bob, O.K. I clued in to what your getting at. I'd keep it on the left. Somebody should come along to correct me if I'm wrong. I know you don't want any binding points or your inner cable won't run smoothly in it's housing and your speedometer needle will get to hopping, not to mention cause unnecessary wear and tear. I'm guessing that if you went out this morning to get at it then you've already got it all done.
Weather!!! I won't likely be riding for awhile yet. We just got another fresh dump of snow!!!
