Go back to the 3 real iron entries requirement to open a class for competition.
List all you want, but race what is really real.
Unwind some of the ridiculous rules for the MC field that were done under the cover of darkness that are not only unsafe but look really bad in the face of the evolution of real materials and bikes.
One seemingly little change caused many many bike entries with existing, long standing records to the rendered illegal for the class they were listed but remain in the book.
The rulebook should be very difficult to change if it is right to start with and unlike some that float the rules to suit their own objectives, when you shill for entries, you cheapen the result.
They seem to have been forgotten but not gone.
It can be done in a snap.
