The fork work I had done by Dan was a great improvement. However I am not sure if I would go that route again.
The only complaint I have is that I still have some bouncing headlight syndrome on some pieces of superslab. Carlos says he doesn't have this issue so I have some doubts about weather Dan has the perfect solution. I have no complaints with the front in the twisties, the bike handles much better, the braking is vastly improved. OTOH my truck gets a harmonic bouncy thing going on on the same strech of superslab so I am not sure if it is really a problem.
I also have not yet replace the rear shock and I am thinking that that is contributing to the bounciness on the freeway.
I think that replacing the fork springs will give you the most bang for your buck and is an easy job to do yourself. Total cost ~ $100.
Carlos can give you some better input on getting your valving redone a la the RaceTech upgrade.
