Okay, I'll be the naysayer. I think it's a really dumb idea to use aluminum in a wearing application. You aren't competing in F1, where ounces matter. Aluminum sprockets on motorcycles don't last nearly as long as steel ones. Granted, motorcycle chains are out in the open exposed to dirt and water, but the fact remains that steel way outlasts aluminum.
How much weight do you really expect to shave by using aluminum sprockets in place of steel ones? Maybe a pound total? Find that pound somewhere else, like fabricating an aluminum rear cross mount.
