Is my bike getting good MPG

[willmckeand]

I've logged almost every fill-up I've done on my restricted '98 Fazer,  my average MPG is 57, so not too bad at all.


However, I do want to take my plugs out and have a look because I suspect she's running rich, on average I fill up about 11L and get around 136 miles out of it......is that good?
