Everyone will know this apart from me but here goes anyway.
When checking for spark I've always kicked the engine over while having the plug resting on the cylinder head.
It's a bit awkward leaning over while operating the kick stand to see if there's a spark especially in bright light.
So:
Take the points cover off, move the engine till the points are closed then just flick them open. If all is well you see the plug spark and you're on the right side of the bike.
I only used to do it the other way 'cos I started out on 2 strokes with flywheel mags and that was the only way.
