You shouldn't get bad mph at 100 now, but 18/40 is going to suck riding in town.

So let me get this right..... You're concerned about your mpg while cruising at 100? Sounds like your priorities are a little off.

I calculate that at an indicated 100 mph you would be doing 108.5 mph with 18/40 gearing
That doesn't take into account any built-in speedo inaccuracy and they're usually about 5% optimistic anyway.
