So far the cheapest way i have found of getting more out of an XVS125 Dragstar is to fit a 520 conversion kit, for those of you that do not know, it is a replacement sprocket set with, if i remember this right, 1 to 3 teeth more on the engine sprocket and 1 to 3 teeth less on the rear sprocket, depending on the gearing you wish. I used the 1 and 1 setting and got an extra 5 miles per hour through gears 1-2 and and extra 10 per hour through 3-5.
