Just thought I would share the results of my mods. I have gutted my stock headers and added a Yoshimura muffler. Had Anthony flash my ecu and installed a power commander fuel controller. The first thing I did was the clutch jumper, bike responded well but a bit grabby. I then had the flash done and the bike ran smooth and became more rideable through the gears. Also woke her up quite a bit. I then did the clutch basket which made a tremendous difference. Finally I gutted the cat, installed the Yoshimura muffler and installed the pcfc. I used the pcfc because I can download pcv maps, create my own and can adjust fueling manually. I downloaded a map for the arrow headers and muffler from the power commander website and I am blown away with the final result. I seriously doubt that the 2014 could be any smoother in operation or quicker. This bike now feels like butter. 8
