Melted ignition stator coil

[George 350]

Bah Humbug.
Booked MOT, rode bike to test centre and 100 yards before shop bike cut out. Pushed to shop and good news it passed with no issues. Bad news is no spark. RAC Relay back home (4 hours later!-breakdown van broke down!).
This morning, established open circuit on stator coil. Removed flywheel and yeuk! lots of black charcoal around the ignition coil.
Oh well, at least it ran well for 11 miles and as my wife said "there is no point taxing it today now".
So off to clean stator up and post it to NLM.
Happy Days,

George...

Bad luck George, hard to believe that the coil can burn itself out to the extent of charcoal isn't it? Surely not enough current? Any chance of accidental contact of inappropriate wires elsewhere?

Subsequent investigation reveals timing side main bearing has gone from perfect to scrap in 12 miles, allowing rotor to touch stator. Haven't dug deeper to find out why yet. This is next week's job while mrs george is on holiday.
