Or.....like I've been saying
FOREVER - Power to Weight Ratio (PWR) classes. Have some classes with a minimum weight per Horsepower, for example there would be a minimum of 5 lbs per Hp in the class shown below:
combined bike & rider weight divided by rear wheel HP375 lb bike + 125 lb rider = 500 lbs / 100 Rear Wheel Hp = 5.00 lbs per Hp
400 lb bike + 185 lb rider = 585 lbs / 117 Rear Wheel Hp = 5.00 lbs per Hp
425 lb bike + 250 lb rider = 675 lbs / 135 Rear Wheel Hp = 5.00 lbs per Hp
450 lb bike + 300 lb rider = 750 lbs / 150 Rear Wheel Hp = 5.00 lbs per Hp
Do that and your going to see a whole lot of competition and a bunch of new people finishing Top 3. Even with the PWR equalized amongst competitors the heavier riders would still be at a disadvantage due to less traction available in turns and longer braking distances, but it would still result in one Hell of a lot closer competition thru out the entire field than there is now. This would also give racers like K3 a chance at winning 'fair and square' due to his ability, not like it is now where even if everyone has the same tires winning can be very influenced by who has the lowest amount of weight per Hp. This would also give heavier racers who currently finish well a chance to show just how good they really are (they might even run away with wins once the playing field is leveled out).
Worried about cheating? These type of classes are about competing on a level playing field and would be on an honor system of stating your Rear Wheel Hp to tech - if you have to cheat in this class then it's obvious your not confident in your ability as a racer. If you want to prove to yourself that your a better racer than the competition, and that your not winning because you have a power to weight ratio advantage, this is where you race. No purse money in these classes (unless a dyno is available to confirm PWR), just plaques.
That's my idea.
