In Need Of F4i Suspension Information
Last year I got into track days and started out on a SV650. I recently moved up to a F4i prepped to CRA specs. The bike was built for a 185lb rider but I weigh 205 lbs.
I’ve got three track days on the bike. The first thing I noticed were how the Vortex clip-ons are mounted above the top triple clamp making the forks look like they’re raised 30mm. I expected this to make the bike twitchy, however I was surprised to find it drifts wide instead.
I don’t know what springs are in the shock or forks yet. Race Tech's online calculator recommends 1.0 kg fork springs and a 16.0 shock spring. I set the fork sag to 35mm and the shock sag at 30mm.
I don’t have the equipment to tear down the Penske shock but I’d like to do the forks. Are there any Must Read threads here or elsewhere specific to the F4i? I’m looking for things like baseline sag numbers, dampening settings, fork height, fork oil weight and level, shock length and recommended modifications.
Also, can anyone recommend a good shop near Springfield, MO? If not, what do you guys do? Box everything up and mail it to Traxxion?
Thanks for the help.

I think it's going to be an awesome track bike once it's set up for me (which is why I traded an '08 bike for it). I'm thinking of taking it to Cafe Racer, Inc in KC to have them help me with the suspension and check everything over. Anyone here have any experience with them?
