Darren, what class would a 40cc aircooled grc mix be in? Just going by the class criteria it appears to be in class 4 as the other classes specify chinese origin. Help.

Yes, Class 4.
Up to 50cc, everything is open.

The reason for the reduced classes is, last year we only had only a few in many of the other classes.
So we have joined the classes where there were only two or three running all year.

In the class you were in, there was only 2 running all year, you and youngy.
So, we combined the 5 port 40cc aircooled with the Euro 50cc w/cooled class.

Reducing or increasing the size of the exhaust tail pipe in stock class is allowed, as long as it doesn't protuded passed the fairing.
