The cables made a big difference - good to know.

Provided the original cables are not internally corroded, then just cleaning up the mating faces to bright metal will make all the difference. After all, they did work once.
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.

Be very careful with the starter motor terminal. If the threaded post turns it could be very bad. Sometimes there is a square on the end of the post to help you hold it while you try and turn the nut.

I second what Gazza said about the nut on the starter motor terminal. If the stud turns it tends to rip out the internal cable connections. Safer to use a splitter or hacksaw to cut the nut off the stud then clean it up well before vaselining and fitting the new cable with new nut.

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.
