other than the rear motor mounts every thing was plug and play,I had it back on the road in less than two weeks that's when I discovered a very dangerous problem. the single disc just wasn't up to the task of stopping a machine that was capable of going over 165mph. phase two, I found a cb750f rolling chassie. it had no title and no body work, I didn't care I wanted the rear swing arm and disc brake setup and the front fork and wheel assembly, I swapped them on my super-K but couldn't figure how to hook up the rear brake. the difference in power, lets just say WOW!! and yes I would do the engine swap again. i had a mac four into one on the 750 motor and used it on the 900 motor, the header sits closer to the bottom of the motor and the filter housing will not slip between the pipes but you can that the filter housing off and turn it down to remove the oil filter, the 900 motor is about one cylinder fin taller than the 750 motor
