Honda Molly is ok to use, but I used antisieze lube yesterday. It sticks like the old proverbial.
I tighten up the bearings to about 20 ft pound, they don't need too much tension and check in about 1,000 kms.
Anti-sieze lube, Mate? Are you talking the same stuff used on things like spark plug threads and other dis-similar materials? If that's what you're using it wouldn't be very good. Anti-sieze compond is abrasive! It will wear out your bearing!
Steering head bearing don't turn like wheel bearings. They only move side to side a short distance. That means most any multi purpose or bearing grease will work fine. It's not very critical.
