Motorcycle Repair: Sportster 1200 rear rocker cover, pushrods, tight fit

Question
I've replaced my front rocker cover gaskets due to an oil leak. Now I can't get the rear rocker cover off. I've removed the top bolts but the frame is blocking the removal of the cover. Is there an easy way to remove the covers?

Answer
Sorry I didnt answer you sooner. My hard drive decided to go south!
The rocker cover will come off without removing the motor. Its a tight fit and you have to turn it to get it out, but it will come out. If you are removing the lower rocker cover you have to remove the pushrods to get it out.
Good luck and happy riding
