It's Snowing

I've had a garage of my own for a few months now, it's incredibly nice. The downside is that it's winter, and North Dakota winter is really cold. I have the Sabre bottom end all together with the exception of a few little odds and ends.
Since the motor and indoor stuff is mostly done on the Sabre, I pulled the motor off the Wards Riverside 175. It's not getting anything special, just a rebuild with new bearings, gaskets and seals. also every part of the engine will be cleaned really thoroughly. I've been getting pretty into trying different medias in my bast cabinet too, and this motor has sort of been my test subject. I have access to beads/crushed glass in the shop where I work, and have glass bead in my cabinet at home. The thing with glass bead media is that it has to be shot using low pressure peened off at a 45 degree angle, otherwise it shatters the beads making it just crushed glass. So the staining and nasty gunk that soaking in degreaser didn't remove the high pressure crushed glass/bead does and the glass bead at low pressure in my cabinet leaves the surface silky smooth and semi polished. However, its incredibly time consuming. The center halves took about two hours of basting with glass bead to get them smoothed.
The cylinder was blasted, primed and painted with VHT high heat gloss black. Also cut all new little round gaskets for the carb along with replacing the weird stock steel wool looking airfilter element with some red uni foam. Also cut a new center case gasket too. The porting isn't too special and there looks to be a lot of room for improvement in the future. The was a flat head screw in the cases that had lost it's head that was free floating around. The leftover stud was fairly simple to remove with the dremel and a left handed drill bit.
Some photos.
