I saw a product on tv called "FLOM" it is slime and styrofoam mixed. You can shape it into 2 tires and never worry about flats, after a little road time you will pick up enough rubber that you will have real rubber tires! You can change the tread pattern to match the road condtions too! I was thinking anout the gas dripping into the heads, you might want to put a pan in the area normal carbs would go to catch the extra gas. might want to get rid of extra weight, fenders,seat,grind the frame,brake system, guards and shields, oil tank and pump, Just put some oil in the crankcase and let it slop around, YOU CAN GET RID OF ALL THOSE EXTRA SPOKES TOO.
