Yep. Mine appears generally to be about 5% more economical with fuel mod, Akraps and DNA stage 2 (given the same riding style and engine speed as standard). However, I dare say if I used the extra efficiency created by the mods to go faster then the mpg would drop.

best i ever got was 78mpg when i fuelled up to the brim and sat at 60mph on a dual carriageway which was pretty flat and slip streaming lorrys etc until my fuel light came on, cant remember the milage.

Mods at the time where

• stg 1 and 2 air filters
• CCC performance cans (baffles in)
• kev fuel mod
• 16 tooth front sprocket
• couple of other non performance type mods.

I think depending on what performance mod it is will depend on what it will do to your mpg. When i first got my CCC performance cans it felt like that to sit at 70mph i didnt have to rev the bike as much and this was backed up by a slight increase in mpg at steady throttle openings. But for up and down revving the cans made the bike drink more fuel, but did sound nice

Interesting. I stand corrected. I am currently looking for an XT660R down here in Lagos. Damn sight more expensive in Portugal is buying bikes.
