The PNWMA mandates that all racers must utilize a spark arrestor on their motorcycle, this requirement is necessary to comply with Provincial law and to meet the conditions of our insurance policies. This requirement will be strictly enforced to achieve a level playing field for competitors and to comply with legal and insurance necessities. The responsibility for ensuring compliance with this policy lies with the club hosting a PNWMA sanctioned event. The host club must inspect each motorcycle at the same time as the sound test. Any competitor found to have removed or disabled a spark arrestor after the inspection will not be able to race, it should be noted the PNWMA does not refund entry fees after a racer has been signed up. Listed below are spark arrestors types deemed suitable for competitors in the PNWMA ORS series.
