So I re jetted my carburetor with the power needle in the middle clip and 132 main jet. Bike is running real good except that the exhaust is popping a lot on deceleration and which I think means it is running to lean (not enough gas too much air). My big question is how do I correctly adjust the stock fuel screw (D shaped head) in the best and easiest way (which correct me if I am wrong could fix the popping of the exhaust problem). If that is not the problem could it be that I do not have the clipped in the correct position. I am close to sea level below 1000 feet.
