i recently installed a 450 carb on a 416ex with a ported head and full yoshi exhaust. it has a dead spot just off idle but pulls really good on mid and top. we dropped the needle the whole way and each time it ran better and better but still has that miss. i checked the main jet and its a 160. think i should go lower? i don't know much about carbs so any help would be appreciated.
