Contact breaker points

Last week, my bike started to run a little irregularly.  I had a look at my ignition timing and found the thread on points for 1 and 4 had stripped and the points were able to float about.  Fortunately, I had a spare back plate and decided to fit it and while there, ordered new points from Dave Silver.

When I assembled everything, I found that the points for 2 and 3 were touching the nut on the end of the crankshaft causing a short circuit.

Looking at the points it seemed that the 2,3 set had a bigger spacer than the 1,4 set.  I suspect they had been assembled incorrectly at the factory so swapped over the points arm from 2,3 to 1,4 and vice versa.  They now fit correctly without fouling the crankshaft nut.

I don't know whether others have experienced problems like this and also whether there are better quality points available from somewhere else?

Bryanj:
Did you buy the expensive Honda or the cheaper repop

florence:
I didn't see the Honda ones on the website, will look again.

Sit down before  you check price

He doesn’t list genuine ones but if you search the part number you can find 1-4 at £34.80 a set plus p&p of course. He has no stock of 2-3 points though. Pattern are around £7.50 a set, which I think indicates the quality of them.

Might regret this but I do have a few pairs of genuine TEC points, I was keeping them as a just in case thing. If you want a pair Florence I’d be willing to let a pair go for £50 inc P&P. Pair means both sets of course. Some are still in bags or blisters packs, most are loose but you can tell a TEC set very easily. Checkerboard backplate and stamped with TEC.

Might be an idea to invest in the Hondaman kit as it essentially means the points should last for many years, so long as you remember to oil the felt pad.
