Engine number GT750-33891 which means it was fitted originally to a K model.

There is no chain break damage and it appears all threads are undamaged.

The cases have been vapour blasted externally and will require a thorough clean to get rid of any residual blasting medium.

The 2 x factory handmade random chisel marks, behind the front sprocket housing, do not line up, so these crankcases were not 

originally assembled / together in the Suzuki factory circa 1973. However the bottom crankcase is from an early J or K model as it doesn't have the o-ring recess machined out at the water bypass hose union.

The crankcases fit nicely together and the bearing mating surfaces are flush as they should be. 

The clutch side lower crankcase mating surface with the outer clutch crankcase cover has some small areas of pitting that could easily be sealed with 3-bond or similar, (trying to be accurate and not paint a picture that isn't 100 percent accurate). 

Please study the photos to ensure this is what you really want to own and build upon.

5 of the barrel / cylinder locating studs are missing. 

At the risk of stating the obvious ****** the engine is empty *****and will require your internal components to make it function.

What you see in the photos is exactly what you will receive. 

It's heavy hence the postage costs. 

Will be carefully packed up and sent via Royal Mail Parcel Force Express 48 hour service.

Alternatively collection from Milton Keynes, Buckinghamshire.
