That looks suitably loud

It will at least sound quick if it doesn’t end up being that quick! Joking with my friends I have built the fastest, old slow bike in town!

If its enough to spill out of the trough its enough, dont forget the starter is not spinning the engine at running speed and the faster the engine turns the more the pump works

That’s hondabond, I only used it on the rocker cover. If it looks excessive I might have been a little heavy handed but the oil looked ok when I dropped it and the filter screen was ok, so hopefully it can’t do much harm there?

I did crank it with the top off as you said and I’m sure there is oil getting to there as it started to spill over ends by the camshaft. I’m quietly confident that there is some oil getting there but is it enough? 

I’m going to sleep on it but I may go with it for now and do a full rebuild in the winter.

It's coming along nicely Roo, I'm looking forward to getting it painted but I think I'll get it on the road to get some miles on it first.  Definitely got an oil leak from the new oil pump o rings so whether I've pinched it when assembling I'm not sure.

That collar and bearing usually need a hydraulic press to remove and from memory there is a small cross section O ring between collar and bearing but its not shown in any books. Honda use to recommend changing shaft with bearing and the cost extra used to be negligable
