We've put 155 miles on the bike and it still gets almost exactly 80 mpg. I lowered the air pressure in the tires to soften the ride after complaints. It's a sort of community/family bike. I rode about 20 miles today adjusting the bicycle computer to match the GPS. The bicycle cumputer is a little faster to respond to change in speed. I adjusted the governor spring that attatches to the throttle by drilling a new hole in the throttle. The engine responds earlier in the throttle movement and opens to the stop now. I do have a 12 tooth sprocket to replace the 10 tooth that is installed now giving a 3:1 final drive vs. a 4.8:1. I also could install the high pressure trick bike tires (80 psi.)
