tlh96 Posted June 29, 2022 Report Share Posted June 29, 2022 I need advice on what jets I should start out on for a brand new 421 cub and how big of a range of jets I should get to get it dialed in. It has 4mm hot rods crank, shearer in frames, noss machine head with 20cc domes, vforce4 reeds, 39 pwk carbs and I ride at sea level. The carbs came with 150 mains and 50 pilots. Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...
