Looking to improve my cruising speed slightly,(lower engine rpm at speed). Which is the best way to accomplish this, raise the front one tooth or lower the rear a couple. I have the stock 17/34 setup on a 1978 XS650E standard. Does one tooth up front equal two in the rear? Are there clearance issues up front with a 18T? I switched from the 3.50X19 / 4.00X18 tires to 100/90 & 110/90 which are slightly shorter than the originals so I will have to compensate for this change as well. Thanks, Joe
