When referring to improving the front end dive, I assume you mean the lack of dive. My bike is a little on the stiff side and I haven't been able to get the suspension to a confident feeling yet, I am a little on the light side at 160lbs.
Are you talking Dynamic or Fixed?
I weigh 195 with gear.
I use the bike for the track so we run in Fixed Mode only.
Front is currently set at 15 turns (max) of preload and 0 clicks (which is max, go figure) compression.
I can BURY the front end under hard braking.
And I mean bury so that the tie-wrap is pounded right to the very bottom of the fork leg.
At Area 27, T-Hill and The Ridge this bike has almost looped me into the tulips because the forks completely bottom.
The rear, on the other hand, is harder than God's head.
Then I get off the V4S and onto my 1199S and all these handling problems go away.
