What sort of tensionor? if its a Protec, theres a guy on ebay USA who i got repro springs from. If its a White Brothers one, it might be the same as the one i have. I found a NOS one I only recognized by shape so bought it. I got a feeling the WB one is something off the shelf they used from a certain model bike for their tensionors rather than a specially made one. I think i know a place in Adelaide that will do a small batch of springs because I know they made a small batch of a 6 or 8 springs for side stands once and i would not mind getting some of these WB tensioner springs made.
