Do any of you know what the stock jetting is on a 400ex? What is the air/fuel screw turned at? Main jet? ETC.....My friend just got his 400ex. Completely stock but when you hit the gas it bogs. Just cleaned the carb out completely and still bogs. I'm guessing its the air/fuel screw. Do any of you know the stock jetting from Honda? It's an 02 400ex. thanks
