1. you need to clarify air cooled vs water cooled displacement limits in F2. and why not allow the 748.749 in lightweight twins also?
2. if you allow 125cc GP bikes in F4, you also need to allow MD250s or custom 250 4 strokes in GP frames.
3. Great job on the 75% race completion for points rule.
4. great job making big bike and lightweight endurance points the same across the board.
