I have a 2006 Harley Ultra with a CSC trike kit. I recently installed an S&S cam kit and every video I saw about adjusting the pushrods said to turn the rear wheel while in gear to rotate the engine. When I tried to do this the engine didn't move regardless of the gear. I also tried removed the seat to give me access to the drive pulleys and that didnt make a difference. Can anyone tell me why rotating the rear wheel won't rotate the engine?
