Now the bike is running I have an issue with charging. The stator that came with the bike had exposed wires as they entered the resin outer of the windings. i.e.the insulation failed. I tried to repair this but obviously didn't!! With lights on the bike will run for about 30 mins before beginning to misfire as I limped home. Electronic ignition systems don't tolerate low supply voltages as well as points do so I guess this was was the problem. Makes sense to me as the ammeter showed a continuous drain of about 4Amps and there's a 9 Ah battery fitted. Getting it going again the voltage at the battery isn't a steady 14Vdc but flickers on the multimeter reading so i suspect the output of the alternator is dodgy. There is a new rectifier, regulator fitted. So I'll need to buy a new stator. The original is a single phase item. Would it be worth upgrading to the later 3 phase (with suitable rect/reg unit) or should I just stick with the single phase set up? Are modern reg/rect generic for both permanent magnet and self exciting type rotors or do I need a type specific one? Sorry, seem to have written an essay again! Rob
