Have an '06',simple matter of cutting 1 wire - don't know which one/mind as it was done at a dealerships.
Can have a look for you c12noon today once I finish my shift. If done/stick with your standard airbox to start off with,start mucking about a sticking something like a 'power' filter on it - WILL kill it low down (take off - mid range)....fly's like hell after/mind - should be looking at c50mph.
Haynes (3492):- Zip 8.5 litres / 2.00 litres reserve Handy tip.?, Whenever you get a 'ped on the road - empty the tank completely,then fill it to the brim,ride around as you would normally at all times until you run out of petrol - that will be your benchmark at what type of range you will have. You can also do this scenario if you riding the nuts off it OR trying to be conservative.
