Guys, I bought a '02 wr426f a few weeks ago. It was jetted rich for where I ride (Hungry Vally - 3000 ft). I twisted the carb in the frame and changed the pilot and main jets. I went from a 48 pilot to a 42 and from a 172 main to a 170. It fixed all my problems except for one. When at constant speed (i.e. dirt road) and about 1/4 to 1/3 throttle, the bike has a miss. If I roll the throttle, it's ok. It seems to be rich just at the spot. Anyone know how I could fix this. Is it the needle setting? It seems I have to take the carb. completely out to change the needle setting, right? Any advice and help would be appreciated. PS. I think the needle is set to the stock position.
