Hi CMG,i think your gearing is way to high,If it was me i would have the gearing set at 200 to 205 at 12500 (in a mile pass) as it will make the bike excellerate a fair amount quicker,your bikes set up to do 344.1 kph or 213.81 mph,im just trying to help you but if it was me i would try 17/48 sprockets,it will then have a top speed of 329.8 kph or 204.93 mph .I think you and the beast have allready done great ,There's a lot more left in her!
All the best Henry and let us know how you go.Dave.
