Putting an HMF on the 350 and a K & N air filter. Running with the airbox lid on. I got the Dynojet kit and the directions say to use a DJ132 main and turn out the mixture screw. Has anyone used this combination? Riding elevation about 1200 feet. I have not decided if I want to use the quiet core or not. Not sure if using it will affect jet size. Any recomendations would be helpful. Thanks.
