I have a 2009 road glide cvo screamin eagle 110 with a stage one air cleaner, Vance and Hines X Pipe and CFR exhaust the bike also has a tune with Harleys race tuner, now I apolojize if I sound stupid about some of this but I am a novice when it comes to engines and the Harley dealer just wants to sell me a 120R and that isnt what I am looking for. From the homework I have done I have found out from Doc that the bike has 255 cams and they dont work well with CFR exhaust, I want more performance but nothing crazy or too expensive so I was just thinking to change the cams? any idea's? recently I rode with a couple of guys that had 09 road glides with 107's and they just left me behind, they said they were shifting at around 4k RPM or even higher and there bikes screamed, they were running d&d fatcats and with the cams it sounded unreal. Thank you for any help you can give.
