750S The Build is Done

Stripped the engine today, oil was filthy, like molasses, internals look good but I still need to mic everything. The big end shells look lile they could use replacement.
Crank shaft was replaced in the 90's, should polish up fine, I wish I knew how to identify the cam, I wonder if it is a B10 or not?
Back to the car washer and four soakings with NAPA aluminum brightener, spotless

Canuck750,
As someone else posted, I appreciate the tips & pointers, the sisal wheel, the 320 grit on a foam backed disc. All these comments do help the 'not so skilled yet'.
Thanks :popcorn:

I really can't take any credit for the tips, most of them came from the real experts in the community, Mark E, Gregory B, Charlie M, Joe W, Rolf H, the guys at MG Cycle, Harper's, and so many more guys who so freely share their knowledge, the Guzzi community is a great bunch.

I flat sanded the base of the block and the oil pan (as explained by |Gregory Bender on This Old Tractor web site), brush on engineer's blue dye, glue some 400 grit sand paper to a slab of granite and rotate the block and pan on the sand paper,
It only takes a couple minutes of spinning, sliding the parts with moderate pressure to get a flat surface
I tore down the transmission,
three stuck 6mm bolts, drilled / ground the bolt heads off, the speed drive head is stripped, ground flat surfaces and a big vise grip got it off.
The inside is a sorry mess, grit, grime,
Most of the bearings are sloppy and have a notch in them
Varsol and then an hour in the ultrasonic cleaner
Soda blasted the cases
The transmission will need a bearing set and hopefully the rest of it measures up ok

That is some good porn!
