What got me on this quest was getting my ass handed to me by my friend on his two seater Helix 150CC. He has a vehicle weight advantage of about 200 pounds but that gets reduce slightly when you consider he goes about 275 and I weigh in at around 175.
My friend said he was going to have to put a horn on his "buggy" to get me out of the way so the faster Kart could get by. I can't have that nonsense going on!
