1mm overbore Middleweight Supersport machines

[racer880]

 At most tracks there would not be that much of a advantage with 1mm over, however at Daytona there will be. a couple horses or ft lbs if tq make a difference on that banking. Kinda suck cause if I am buying pistons, boring and plating I would rather go 2mm. Anyway good job CCS for pulling this off.

i think they ruled that you can't do 1mm overbore for the 200. Am i mistaken?

This survey and inquiries to engine builders and piston manufacturers is being done to investigate change to rules that currently allow 1mm overbore upto class displacement limits.

Jan 5 for all rules but will try to get word out sooner if possible.

As long as the Kawasaki 636 is legal I don't see why you would ban +1mm overbores up to class limits.
