the noise restriction (I'd go for 96 or 98 dB) would solve your problems. You wouldn't need to change the displacements.booneyscb said:Maximum noise level regardless of rpm of 100 db would solve any disparity issues as to class structure for 2 stroke versus 4. If anyone enforced the noise rule in Indiana more than 60 % of four strokes would be illegal.
Propose limiting 250 four strokes to 225cc for 2009. 450 four strokes to be 400cc at the same time.
Bring speeds down. Slower speeds equal better racing. Have less injuries. Have repeat business at your track.
