My downtown allways ran well, it was the electrical that gave out, it ran better every year after year, that is why I am rebuilding it, it never used oil, even with a slow leak, from the crank case, just below the fill hole, I broke it in hard, first 25 mi;les up a steep hill at 65 miles then down the hill at 65mph. with closed throttle then changed the oil, next change at 50,.,, 100,., 200,. 400,. 600 the dealer did it for the warrenty,. I played with the variator, changed the ramp so the sliders went right out for high gear, my rpm is 65 mph at 6000 rpm , at 6500 rpm 75 mph,.
