2023 Cor PowerSports Handbook changes (all updates highlighted yellow in handbook)

Fuel jug rule (Pg 13)

  •  New LC2 cans are different than LC can in rule; New LC2 cans have a larger vent so they flow at a higher right than the current LC can allowed

Class Advancement (Pg 17)

  • If a rider wins a class championship in Sport or Semi Pro divisions you have the following season to defend that championship, finish top 3 the second season and then bumped up to next division. (takes effect immediately, 2022 class champions can defend their championship for 2023 season)
  • To move down a division a rider must submit in writing a request to Cor PowerSports stating the reasons they feel that they should be allowed to drop down a division. This will be a decision made by the Cor PowerSports race director, if you drop down a division without approval you will be disqualified and forfeit any entry fees, points, or purse money earned in the lower division.
