I decided to try and tackle the rotor mod. Well I think I have the most stubborn 1125 of them all. Getting the rotor nut off took me awhile and once I had it off I had to go get a gear puller to get the rotor off. After all of that got everything back together fired it up and it spit oil all over the place. I ended up tearing the gasket, the local HD dealer didn't have the gasket in stock so I decided to order on through American Sport Bike but thought it would be the perfect time to go ahead and order my barker exhaust also.
