Revision to X30 Header/Flex Rule Posted 13 December 2018 Print
Friday, 21 December 2018 11:18

We recently posted a change to the allowed Header/Flex length rule. After receiving additional input from tuners, competitors and engine builders we have decided to standardize the length for all X30 classes to 17” MINIMUM. Note that this change will be in effect at the Winter Series Rounds1 and 2.

This measurement is taken from the outside of the header flange (not the engine side) around the right side of the header, Flex and exhaust to the weld at the first divergent cone. Measurement is taken with exhaust as installed on kart.

A reminder that SKUSA rules do not allow solid connectors, flex must be used as supplied with engine.
