Hello,
Yes it turned out to be the exciter coils on the alternator stator not generating sufficient voltage. I can't remember the actual figure now. But I put on a spare which I think gave 80v at cranking speed which was enough to give reliable starting at all times. I am not sure why the coils deteriorated gradually to a point where it would not start rather than failing completely.
Are you having problems?
Richard

Not problems of that nature, but my bike is in having the starter gears fitted, they’ve been done now but it appears the starter isn’t strong enough to turn the engine, it apparently starts on the kick start but whether I have the strength to kick it over yet is debatable and the reason I sent it in the first place to have the gears fitted, so it looks like I may have to source a new starter motor.
It used to whizz over when no gears were fitted but then again it wasn’t under load, I’m guessing it wants an overhaul of new brushes and cleaning but that could be a later project for me at some date.

Congratulations on sorting your starting issue and thanks for posting the outcome which I have noted for future reference 👍

It is quite an easy job doing brushes etc, and is only slightly awkward getting the starter off. I always find it more difficult refitting the starter without removing all the cases but it is possible.
If you're starter is actually faulty, I have a few which might help you out. Where do you live?
Cheers
Richard

Hello, I looked out some plates ages ago and can't remember where they are now. Sorry about that. I'll have another look.
Cheers
