Best way i found was
Performance cans
stg 1 and 2 air filters
kev fuel mod
1 tooth larger front sprocket (the extra grunt from the above mods still allows the bike to shimmy!!!)
The added power and higher (or correcting) gearing allows you to short shift or reduce the need to rev the bike as much, keep a steady speed, and fewer gear changes and better ahea planning. oh and 60-70mph with 1 tooth+ front sprocket.
Using this combo and a fill up to fill up in one long steady ride saw me get 78mpg while fully loaded!!!!
