Old TAG classes?

Is anyone aware of a class that uses out of production TAG motors? I have two old Leopard’s and got to thinking a class like TAG sportsman that uses only out of production TAG motors and maybe a harder tire compound might be fun and a little less intense than the typical TAG senior class.


F-Series Gearup which is up in my general part of the northeast runs (ran?) Leopard in Ironman I believe. Last leopard holdout. I believe it ran against Rotax and x30 at a lighter weight?
