If you're not gonna add much, the stock system should do ya... In all my reading glhonda has had the most success with changing stator's as he's changed about 5 I believe on different GL1200's and had no failure's yet using Rick's Stator's. Here's a link:
As far as increasing the stator wattage?? I'd stay with the OEM 360 watt output as I think you'll have a problem later with the regulator not being able to handle the additional wattage,,,, Oh, and one more thing.. Make sure you solder ALL the regulator and stator connections!!
Hi storm714, for me I removed the faulty stator and had it rewound and saved a lot of $$ by needing to have one sent out,(to NZ) but perhaps where you are a replacement stator is the way to go. Do check the standard electrical/stator "mods" tho for the 1200,(on this fabulous site) or you may find yourself needing to replace again down the track, as you are probably finding, not the best thing to need to do.....(replace the clutch seals tho with the engine out..) My understanding is that if you choose not to go with the alternator mod (and with LED lighting technology,maybe it is not necessary) the LTD uses a higher wattage stator which you can fit, but has a different regulator, so you you would have to replace both, and possibly some wiring (a guru will chime in to let you know this I am sure), but, as the output of the stator is maximum at all times,(unlike the 1500 and up which has a "fair dinkum" alternator) do run your electrics up to the maximum output of your system, that way the stator does not run hot (as the unused current is grounded to the frame of the bike, and the heat generated can assist in shortening the life of the stator). You may wish to install a voltmeter also to "keep an eye" on things as you go.
