I have the 14 with a PCFC fitted and dyno tuned, I have dropped one tooth from the front sprocket, I have a Scorpion slip on and standard air box so we are very similar.
I don't much talk about fuel consumption, if I'm burning fuel I'm having fun so I try to burn as much as I can.
I only keep rough numbers and do them on long rides just to ensure I can make it to the next fuel stop.
I didn't have the bike long before I dropped the tooth so I don't have any stock numbers, with the slip on and after dropping the tooth my rough average was 5.5 litres per 100ks
When I fitted the PCFC and used the inbuilt map that suited my bike EG; stock filter & slip on muffler my fuel consumption skyrocketed, there was a improvement in performance but I could tell there was more to come.
I had the bike dyno'd and a custom map built, over the PCFC map I gained 4 HP, that was nice but my torque is where things got going, it was moved to a earlier and more usable RPM and in the lower RPM's it almost doubled, from 29 ft-lb of torque to 49.
Although the bike is now more fun to ride my fuel burn is the same as it was before the PCFC was fitted.
I'm a fan of paper filters and need a very good reason to get away from the stock filter system, in my case I'm more than happy with the results the custom tune got me.
As I said don't look to deeply into my fuel burn, every opportunity I get I'm at WOT.
