The 73mm may be the route i end up going. A 181÷74×6200 is just above that at 15,184. I wish we could get into more custom crank pulley sizes. That would make fine tuning much better.
That's a good idea, if someone could come up with a pulley that had a spline that you could just slip a different size pulley onto it. Interchangeable sizes and just a few minutes to change. Maybe this would lead somewhere. I don't know if my machinist friend could or would want to give it a try but there could be pulleys from 74 (stock) all the way down to 62 or so.
