I worked a lot on suspension setup, rear suspension made the rebound faster, front took out some pre-load and added a little compression....
Changed my gearing a little in the rear, went down a tooth on Sunday, really helped when trying to get the power down and not spinning up the rear tire!!!
This is a 1000cc bike your mileage may differ
Also worked on sections of the track in each practice, asked around and observed what lines looked faster to me...
seat time, seat time, seat time!!!
