[QUOTE="oexing, post: 169245, member: 1493"] Honestly some arguments look a lot like religion, balls or taper bearings. When you look up steering bearings in Ebay and all , you only find ball types on mopeds or light motorbikes. So I don´t believe in problems from taper roller bearings , instead I think these are better with radial loads and less critical with setting them nicely. I just got sizes from the standard Vincent stem which is about 28.5 mm . So this makes it suitable for an adapter for 30 mm i.d. taper roller bearings. You´d get the stem on the lathe and maybe remove the old step for the ball bearing inner race. Then turn a bush with ~31mm o.d. and loctite it on the plain stem. Next day you can finish it for exactly 30 mm light press fit for lower bearing and same bush for upper bearing, light slide fit. No need for the stem to be perfect and straight, just for Loctite application. The link below shows a Yamaha RD 350 bearing with o.d. 48 , i.d. 30 mm and 12 mm height. So this can be used for standard stems and Norman´s mod as well. Just you need two sets of the Yamaha kit for two of the right size on Vincents. Certainly another adapter in the head lug is required for adapting from 50.5mm (2" ) to 48 mm , again loctited in. So no machining the head lug is needed. Another plus with taper type bearings is the large area of fit on stem or head lug. The ball type races are just around 5-6mm so they often eat into stems or recesses , so then big headscratching with loose bearings.
