just got my hmf pipe and was wondering if it mattered which way the spark arrestor went. i have it in there with the bubble going into the pipe.
also the jetting that hmf reccomend for me ( no airbox lid, k&n filter ) is 170 to 175 at sea level. that seems awfully big to me. but he may have told me the jetting for the 400ex since he quoted me the price for one originally.
