Honestly,I have tried so many different ways and made so many posts about it, lol. What finally worked is one day I looked at all the time slips and the 60ft as still pretty much the same regardless. I had the suggested 16-42 like everyone else seemed to suggest but it did not work for me. I jumped to a 16-45 and dropped my average 60ft to the 1.5 range first day out. Second time I ripped a 1.50 on a beat Shinko so I knew that I was on to something. My normal was in the 1.6 range before. I am now trying for mid to low 1.4s. I only have a few track days on the 45t so it will come. High 1.4s are now ok but I see what it takes for my individual weight, riding ability, length, etc...to get moving. I have not even messed with my stock shock settings, weight reduction, etc... Should be fun.
