About 10,400 on my 2012 LIKE200iLX, no screen, bigger top box, a few pounds in OEM crash bars, 250lb rider who never rides full throttle.
Running Dr Pulley sliders and an NGK Iridium plug with stock CVT parts. Michelin City Grip tires. (26 & 32 psi F/R)
Do not know how any of this affects fuel mileage. My valves are adjusted and the air filter is clean. AMSOIL in the engine and Honda Pro gear oil in the rear. When I was still filling at the gas pumps I was getting @71 mpg. Now that I avoid filling stations for home refueling I have no idea my MPG's.
If you run the engine hard your 60 mpg sounds about right. This is not the most advanced engine set up, even with the EFI, but it is pretty darn reliable. Keep an eye on the oil and change a good brand of oil often - it is the life-blood of this little aircooled engine! Cheap too, at less than a Qt per change. If the LIKE was water cooled KYMCO could likely have improved the fuel economy - but the aircooled simplicity was a selling point for me.
Per the owner's manual you should have your scoot's 2nd airfilter in there at 4,200 miles. Necessary ? Who knows - but KYMCO advises.
Some say to increase the psi in the tires for better MPG's - but this just shakes the crap out of the scooter and the rider IMHO.
Pictures?
Ride safe, Stig
PS: your GPS top speed sounds spot on to me.
