The joys of powder coating. Spent a few hours (and a few COVID beers) re-tapping all the holes and sanding off the powder coat from bits that aren't suppose to be coated. I've ordered in Taper Steering Head bearings in to replace the original free ball type that Suzuki used. It required a bit more material to be taken off the stem. Only just managed to get it to fit in my lathe as as the stem is welded to the lower triple - if it was any bigger I would have to take the gap bed out and use a drive dog (far too lazy for that).
