Rear air pressure at 20 or lower. You have the power to be in the low teens for air. Also turn up the preload on the back so the tire comes into play before the chassis finishes squatting. If you can preload the front so there is no extension on the hit it will get on the back tire better.

A strap will help keep the front end down. You can buy the strap brackets for your forks like I have. Will help a lot

I also found some more HP, turned up the timing, took off the air filter, and fed it more fuel, I wasn't as fast on the 60 but made more HP up top, just need to hit a solid 60 and run 128 and I should be right there with Chris around 10.1-10.2
