  • Big 2 Stroke Slug

    Got this one in an 89 CR500, first over at .0025 wall clearance. Maybe a little tight but I broke it in right and now super quiet and running perfect. Key to long life, esp in a big bore 2stroke is slow warm-up. Resist the temptation to get revvy with the throttle when cold. The piston expands faster that the water cooled cylinder then binds or cold seizes in the tight bore. I found tiny cracks on the intake side of the piston skirt on the stock piston from the original owner. Caught it before it came apart and lunched the whole motor. I've run thousands of laps on moto courses for years and have never blown a motor. I get holeshots too. Jet a little fat and always warm'em up well before buzzing the motor. With an exhaust bridge, drill the holes on the exhaust side also for extra cooling, I run 927 oil at 32:1 and a dash of 110 fuel mixed with regular gas to just prevent pinging. Keep fresh reeds and repack your silencer often with R19 pink insulation for quik response. .k
