Unseizing A Motorcycle Engine - Barn Find CB750 revival! The $100 barn find CB750 takes a big leap forward in this video as I work to unseize the engine which had sat for years without spark plugs exposed to the elements. It appears that cylinder 1 and 4 had a bit of rust holding the piston rings to the cylinder walls causing the engine to be stuck.

After soaking with Marvels Mystery Oil for a while I tried working the engine loose and was successful after a few "polite" taps with a hammer on a long prybar. Look for more on this project in the future!
