But CCS has already set precedent by allowing the 600 in LW F40.
Yes, But as The Powers That Be have stated, LWF40 and TB are a mix of LW and MW, since they are sportsman classes.
You must remember that every time a rule is changed, they have to figure out every way which that rule can be applied to various bikes or combinations of frames / engines if swaps are allowed, which they are not in most classes. That is why it's difficult to get the rules changed. Look at the 500 class and all the drama that's going on there with what will be allowed!
WERA allows frame and engine swaps. CCS generally does not.
Too bad, we'd love to have you down here and we would welcome more participants in the LW classes.
