My VTR's forks have RaceTech gold compression valves, 90 kg/mm. RaceTech springs and stock 4-port HMAS rebound valves. I've changed the shims on the stock rebound valves and the brand and viscosity of fork oil. I don't want to drill bigger holes in the stock valves to get increased flow.
I'd like to try the 3-ports. Anyone have any for sale? I know the smartest and easiest thing to do is to send the forks to Greg or Jamie and the second smartest thing is to buy rebound valves from RaceTech or Ohlins.

 

Not sure about the valves but did you try grinding the point of the rebound adjuster to remove the step? There is a write up somewhere about it.

 

I did that a couple of years ago.

 

Why not just buy some oil and a couple of shims and revalve it yourself?

PM me for details.
