Tip #2: Power to weight ratio really does effect performance and maybe more than you realize, I've been told that in race cars every 10lbs. lost is like adding 1hp, with these kits and working on a much smaller scale weight and hp wise the change in performance could be more or less noticable, I highly doubt that the less than 3hp engine could be comparable to a 10hp motor if I dropped 100lbs but who knows? 3 hp with 150lb kid on it vs a 10 hp with a 250lb kid on it with all other factors remaining constant (gearing, fuel mix, aero dynamics) who would win? I guess the bottom line is we could all lose 10lbs and its not gonna hurt nothin lol[/QUOTE]
I did notice one thing while trucking I got the same fuel economy or very close to it even when fully loaded because the same weight that holds you back going uphill pushes you even faster downhill. Now this is if you let it fly downhill which I did LOL. I remember going thru some mountains 85 MPH downhill and 15 uphill.
