I just bought the 2 into 1 supermeg for my ultra and running a 124 in it for three years using a pro pipe. I just tired of the noise so went to the supertrapp. I have been changing discs for a week now with no luck on the bottom end to low mid range 1000 to about 2800 rpm. Running closed cap that came with it and 20 disc's and been up to 24 which was better , tryed all the way down to 16 did not work at all. Running 22 and was ok but found plugs running lean with a super g with a .033 primary. Any body have an idea how i can richen the mixture up to gain back the low end. I just stepped up to a .036 with 24 discs tonight and give that a try.
