Last Saturday I went for new air filters and a new (injection) mapping. I was planning to get that done anyway, but then I decided to update my blade with two K&N filters also. Slightly more performance and little to no more maintenance needed in the future regarding that area. (And honestly, while the filters are much more accessible then at my previous bike. It's still not the most fun part to clean.) After approx. 2 hours they finished tuning and she took one more run on the Dynojet. A total of 165 bhp on the rear wheel and (the most valuable part) a much faster throttle response and better power outtake.
It was costly for something that seems minor, but as soon as I drove off and noticed the difference it was all worth it!
