The connections suffer from Verdigris building up and adding resistance. It comes off fairly easily with a wire brush or some wire wool.
New leads should also be connected to bright clean metal.

Mr G is quite correct in this however, certainly in my experience of swapping the leads (I made my own up at work) on my 1997 900 the original wires were of marginal cross section, all the terminals were Brass (rather than better conducting Copper) and after the twenty years or thereabouts when I changed them and without properly sealed ends there was always going to be a fair amount of internal corrosion.
I didn't actually measure the resistance before I changed them (I wish I had now just for my own record) but my bike has never started so easily in all the years I've owned it.
