On my ES I put it in reverse and get going to about 6 mph then I try to put it in neutral if it doesnt do it right off its just cause its reved up to high. I keep doing it as Im rolling backwards then after its in neutral I let it roll a little bit more and then yank back on the handle bars and shift into first. If I stand on the back racks I can throttle it for ever but only about 4 mph. Ive tried shifting into second, but it goes over on me. Try it and see what Im talking about.
