2019 RULE UPDATES
July 10, 2019
Briggs & Stratton 206 Clutch Clarification (Non-Impacting) – It was brought to our attention that a clutch system recently released on the market was being sold as being approved by Briggs & Stratton Racing. This clutch, called the ‘snap yo neck’ was never approved by Briggs and Stratton Racing and is non-compliant to the Briggs & Stratton 206 rule set.
To prevent any future marketplace confusion we will be working with original clutch OEM’s and publishing a list of approved clutches which will remain locked for a period of time. This will help to insure stability and cost-effectiveness, two key cornerstones that are fundamental to this program.

Driver will be scored as a mechanical DNF for that segment of the event and he may repair his kart and continue in later segments without additional penalty. All bodywork must be intact and in correct position at Technical Inspection at the end of the competition segment. Failure to heed the mechanical black flag will result in the kart/ driver being shown the Black Flag, 109.4, with associated penalties.
