I plan on using the Dynojet needle with my stock jets. I am moving up one on the pilot because I read that the float bowl overfills on the Raptor 350 with the thinner needle. I read someone on the forum used a 155 main with his stock needle. I do not believe I need to go that big on the main but I am not sure how much smaller to go. It ran pretty good with the stock main. Just want to be sure I'm not lean. Any one else try this?
