In this episode we are joined by Oklahoma's own Marshall Plumb, owner and operator of Marshall's Racing in Stillwater, OK and one of the organizers for the Oklahoma State Championship Series. However, most people outside of Oklahoma probably know Marshall as one of the most tenured members of the professional motocross and supercross pits. Marshall started his career as a mechanic in his home country of Canada and later moved to the US where he tuned Guy Cooper and Bryan Swink to national championships in the early 90's. He remained a professional mechanic through the late 90's and eventually landed at Dunlop Tires where he still works on the weekends today. Marshall has an incredible story and the Oklahoma moto scene is fortunate to have him.
