The mag. on the GF bike has been rebuilded 3 times since 1993.
On time by a Company in Sheffield cost 290 £
lasted two years.
Next time 1996 SRM, new amature, re-magnetized, oil seal, bearings, cam ring , etc etc approx 500 £
Rebuild again 2005, at a cost of 450 £
Beside that it had used pick up units ect..
Now it need to be re-magnetized again.
Sending it to the UK and waiting for months before they bother to rebuild again, sent me in a other direction: Electronic ignition....
See the same issues with my other bikes.
Lost magnetisme when standing for long time unused.
Mag. demand a lot of attenchen for few miles.
"Modern" fuel with high content of ethanol 5% , and now changing to 10% , demand a strong spark when starting.
There is a modern magneto that might last for years without issues:
