Consider Race-Tech Gold Valve kits, or Ohlins valve kits.
You may also consider Kyle Racing valve kits as well since they pattern theirs on the Ohlins valve kits.
You may also change the springs to suit your weight.
Also Ohlins #4 fork oil is great for normal riding to average track days (per Ohlins).
Springs will run aroung $100 ea.
Race-Tech compression and rebound valve kits run around $190 ea.
Each kit contains a pair of valves for each function (i.e. rebound kit has 2 rebound valves, same for compression kit).
