Ce n'est pas ma théorie
Je pourrais en traduire des bouts plus tard...

At least another 20 threads on the same subject but the bottom line is that the stator overheats mainly due to the fact that there is insufficient oil sloshing around the stator. Honda resolved this issue with the MKII. Hold onto your gears a bit longer and keep the revs a bit higher - generally put, revs below 4/5k and oil flow into the stator chamber is poor, above 5/6k and the oil flow significantly increases (there is a thread somewhere on this as well) and the only consistency that I have seen over the years is that those who ride their bikes a bit harder appear to get a better deal than those who pootle about. Also some say that a replacement stator from Electrex is better made than the Honda one but even those are reported to have failed, others recon the regulator could be a better design and both these points may be so but there are lots of MKI Biffers around still on their original stators and have done high-ish miles as well.
Honda eventually recognised the issue and increased the warranty on MKI failed stators to 7 years (2 yrs + additional 5) and replaced both stator and flywheel with modified units which significantly improved matters but it was not until the MKII came along that the internal crankcase oil way to the stator was increased was the problem satisfactorily resolved.
Given that a replacement non Honda stator is £125 or less and it is a simple job to replace (2 out of 5 spanners difficulty on the Haynes service manual scale of difficulty) and the fact that you can get a little warning of imminent failure from the MIS light flashing at you or BETTER still fit a £15 Gammatronix or Sparkbright LED battery/charging warning light it is no longer the big deal that it was in the earlier days of the MKI.
