Sinto are you very small and light? Might explain the miracle numbers
I am indeed
Probably no more than 11stone with full kit and only 5' 5"
But the other reason for the miracle numbers is I've increased the size of the breather hole in the neck of the tank so I can fill it right up
Was only getting about 180 including warning light mileage till I done that.
Things I would say are....
When you fill it, always do it on centre stand
For say the first 50 miles or so, always use the centre stand.
If you don't have a centre stand on your bike, DONT DO THIS MOD as when you lean the bike over, the fuel you've got at the top of the neck/tank, goes into the overflow and then runs out through the pipe to underneath your bike and then you've just lost all the advantages of doing the mod.
I know from past experience
