Chrome O, This is just my opinion, but it seems like a lot of time and money for a small improvement. I have an 09SEUC (silver). I did the fullsac/mastertune/1.75 inch baffle replacement and HD free flow air filter (with K&N filter ). I am going to leave it at that and if something breaks after warranty is out then maybe some Andrews 54 cams/ Headwork. It seems like a lot of people, including myself on occassion, want to take a product that was designed for a certain use and turn it into something else. I guess I am just happy with my bike the way it is and find it hard to understand why so many people want to make so many engine upgrades, especially while under warranty. I can understand changing things like seat and suspension changes, but if you have a good running motor why take a change and possibly make it less reliable. Just my 2 cents combined with 4 beers. Good Luck whatever you decide. CAHDBIKER
