My '74 Commando came with a 20 tooth countershaft sprocket which I changed out for a 22-tooth a number of years back. Now I am having second thoughts about this conversion. The 22-tooth definitely makes for relaxed interstate cruising at speeds above 65 mph or so but I am finding the gearing a tad tall for the 2 lane twisties. It also requires a significant amount of clutch slipping to get it moving. Since I am spending more time riding the latter compared to the former, I am thinking of going back to a 21-tooth or possibly the 20-tooth.
So my question is this:
What are your opinions about optimal countershaft sprocket size for an 850 Commando that is ridden primarily on secondary roads at speeds from 55-70 or so? My understanding is that US-spec Commandos generally came with 19 or 20-tooth sprockets but that Euro spec models had 21 or 22-tooth sprockets. Any and all opinions much appreciated!!
