For the past few years I have been running an 1100 cat triple on the asphalt. This year I moved into a 1412 triple that a guy in my shop has ran for the last 2 years. The sled has never ran faster than 9.0's at 2800' of elevation. I spent the last two trips out at the track dialing in the suspension for me and I'm ready to start working on the clutching. I am curious as to what other people run for spring rates in the primary on a big motor. Right now the sled is setup with a 75/290# spring in the primary and engages at around 2400 rpm. I've got a test and tune coming up in 2 weeks and would like to make some progress. Last time out I ran a 9.09 @ 144 with a fair tail wind. I want that 8 second pass already :). Anyone care to help me out?

Thanks!
