Hi Norm or is it Ozzy?
Can't see much wrong with 60mpg, in standard set up (standard exhaust and variator) you should get between 40-80mpg depending on speed and terrain your riding in.
I managed 116 mpg while in Ireland the other year, 30 mph all day sight seeing with small throttle openings and that was 2 up. Blasting down the motorway at full throttle and the **** thing drinks the juice.
I get about 100 miles from a tank on the motorway, have you noticed how the last half a tank doesn't last as long as the first half?
Got to strip the engine down over xmas to replace a few gaskets as I have an oil leak
