Ok, since I had to park my bike for the summer and it will take me a while to get my engine rebuilt the way I want it (damn grinding noise from the crankcase). Anyone have a clue how hard it would be to drop a DOHC 750 engine in for a summer? My dad has a spare one sitting under his garage steps and I would like to be able to ride next year even if the engine in my bike has 1 to many cams in it. I'm guessing the ignition & carbs will be the hardest part since the DOHC engines use the stupid ignitor boxes. Carbs will require a trip to the junk yard or a piece of steel to make a new bracket to mount them all on.
