While rebuilding my shabby shadow I find I will need to use some loctite or similar on a spindle or two. Reason being the hole is just a gnats hair too small for a 2 thou oversize but too large for a 1 thou. This is a low cost rebuild OK. Do I use Loctite 620 high temp. or 660? I am leaning to 620 but prepared to listen to those with more experience. As far as I can see the spindles need to be located to allow the cam followers and cams to rotate and do their job. If the spindles are fastened to the steady plate and all moving parts are lubticated with clearances there should be no problem. There are two studs that set the steady plate in position plus the half time pinion so if all other spindles are set at their 0.491 " from the timing face or thereabouts all should work. Or not? The bike was running like the Mallard before I pulled it down; smoke and all. 90mph in 3rd gear was something I had never experienced on a Vincent before.
