Most of us have already raced the antiques that you want to use as an excuse to boot out better machines. That was then, this is now. I think we're breaking a record this winter for whiney LW threads...and that says something.
I don't think you understand what I would like to see. Let me spell it out.
Aprilia cup bikes, Motards, EXs, HAwks, and FZR400s would be in a Sportsman class with SBK rules
Ninja 650, SV650, Duc800 in LWSS (also ULWSB but limited to SS rules)
air cooled 1000s 1100s 1200s allowed in LWSB
everything above allowed in LWGP, Thunderbike, GT Lights.
i listed the class limits, and of course you can raise up for additional classes.
