OS Valves

Does anyone have a lead on OS valves, it seems as though KW or Ferrea are basically it and those are one off. I'm thinking that the VTR valve might be similar to something else out there, is there a way to search valves by dimension? Or does anyone have a set of HRC's for sale?

Thx

Unfortunately Ferrea blanks cut to spec was all I ever found. VTaRse (here, Tony.Mon on the UK site) is one guy I know that found some "on the shelf " valves and that was in the UK. I read he got the last ones a race shop had for the VTR. They had made a run of oversize intakes for the UK guys racing the VTR at the time. Ive sent him a note to confirm what I remember...But thinking your not going to find an off the shelf option

Hi, Erik.
I found the original source for the valves used on Rogers race bikes.
They're called GA Valves, you should be able to find them online.
Happy hunting!
