I have a similar pictureI got a good second hand alternator from motorworks
I've put a wanted on the site, will see what happens, but might well end up doing the same. Have used Motorworks before and found them very good.
New ones are £430, Motorworks are around £200.

I hadn't used the bike for a while, when I did found the alternator seized. Has a crack in the casing. I realise I'm going to need another alternator and that its not repairable.






Will now be keeping her covered on the centre stand and starting her up at least once a week
