Posting this up as few have stated that the andrews pulley is a issue. Well I can tell you that I have two touring bikes that have just over 20K each with the 30 tooth front pulley from andrews. Guess what no issues at all. I had hoped there would bve none but being that I read this back when it was posted thought I would add to it. The HD part is less money , but if you come across a andrews pulley for a good price nothing wrong from what we have seen first hand. BTW on my own little 107 making near 125/125 the andrews pulley is holding up just fine with a goodyear belt from drag on it. I have no idea what others are doing with belt tension , how they ride the bike etc. My own bike I beat the hell out of it every chance I get.
We did a 110 with the andrews 54 and the +4 key back to back and the numbers laid right on top of each other. Now you may change a pipe and find the missing power .. or not unless you test it back to back you will never know.
