I just had S&S 509 gear cams installed on a 2002 88 FXDL. the bike runs nice, however i do not get the engine braking on decell that i used to. I am thinking the guy fooled with the carb and the slid is not coming down as fast, but I am not sure. I do not thing the cam would cause this. I am thinking of hitting the kill switch and see if it decels it would probably rule out the cam. Any suggestions?
