Hey guys - just signed up here, and haven't done the formal intro yet, but this is JD from PanikSwitch Cycles, mentioned above. We're also working on a "universal charging system upgrade" as well, here in the Hermon/Bangor area. We just did a 73 CB450 upgrade, using a more common Suzuki GS1100 rec/reg...instead of the puny 12 v output, she now puts out 13.5v. I just picked up a pair of 74 CB550's myself, and will be working on a wiring diagram for the same upgrade for the 74-77's. As soon as I find a supplier for decently priced reg/rec's and the proper connectors, I'll start making a few up for sale. Feel free to email us with any questions or tips (info@panikswitchcycles.com).
Also, thanks a million for the recommendation "wowbagger"...it means a lot when we see people putting our name in the same sentence as "top notch"!!
