Pro Mod Rules: 

All bikes must pass basic NHRA tech inspection (performed by track official).  Belly-pan oil containment is highly recommended on power-adder bikes (and may be required in '07).

In addition, Pro-Mod bikes must meet the following weight requirements.  Bikes may be weighed after any passes to check for compliance:

Normally Aspirated........no weight minimum
Power-adder, 9" tire.......600lbs bike/rider min.
Power-adder, 10" tire.....625lbs bike/rider min.
Power-adder, 11" tire.....650lbs bike/rider min.

Gasoline or Alcohol. No nitromethane permitted.

Racers will be laddered on a standard NHRA Pro Ladder (all-run). Lane choice is determined by best ET in qualifying, and by best ET in previous round for next pairings.
