I’m just curious: why would spinning the wheel backwards make a difference?

It draws the lube into the links

Does it not do that while spinning forwards?

Thinking about it, I always used to do that, back in the '60s - spun the wheel backwards, lube the bottom run. I suppose my thinking then was the sharper bend on the engine sprocket permitted more extreme movement of the links to draw in the lube better? But this is all a bit "anal", isn't it? I was very anal then about all aspects of motorcycling. As I'm older, I'm less so now!

I think, there is some relation to where you're living, northern or southern hemisphere. It has something to do with the Coriolis force.

Django...

Django could well be right. It's very comforting. I'll keep oiking the bike onto the centre stand, starting it up, putting it in gear and squirting oil all over the place. And because of Coriolis, the wheel will be turning the right way!

If you run the bike in top gear at 8000 rpm with the garage door open you will lubricate the whole neighborhood.

Come to think of it, I used to pull the rear wheel backwards and spray at the rear sprocket equator. In general, I don't care because I am not too passionate about chains.
