As of September 2017 TSRS will require all Briggs and Stratton classes to seal the top end of their declared race motors for each race using the provided picture diagram as a guide. Bolts shown on the diagram will need to be drilled in order to complete this sealing process. Seals will be provided at each event for all racers and do not need to remain in tact once final technical inspections and the event have been completed.
