CB/CL 77 vs CB/CL 350/360 Stator

[sarals]

A recent post by Vince Lupo has caused me to start looking into upgrading the charging system on my Superhawk. 12.8 Volts maximum isn't enough, the battery does go flat over time. Vince mentioned he uses with great success the Rick's Motorsport stator, P/N 99-102, made for the CB/CL 77. However, it's no longer available. They have another stator (and regulator rectifier combination), P/N 99-101, which is made for the CB/CL 350/360. It looks practically identical to the 305 piece in the photos.

Does anyone have any experience with the 305 and 350/360 stators/rotors? CAN they be interchanged? My guess is there wouldn't be a different part number if the pieces were interchangeable, but maybe there are easy to do mods?

Thanks in advance!

Umm; yes, no and no. you need to live with what you have. first, get a solid state rectifier. then, if the stator is peeling or looks damaged, try to get a better one. last ditch is to start swapping rotors. typically these things need a boost charge once in a while as the stock system (50 years old) really isn't going to perform like a modern system. my CDI bikes can sit for a year and start right up, the 305's, not so much.
Good luck

Hi Randy! Thanks for that! The stator is physically undamaged on my bike, and all legs produce right at 60VAC (measured directly from the stator harness). I put a new bridge rectifier in place of the original selenium rectifier long ago, and I also have a regulator rectifier stashed away that I had originally installed to replace the stock rectifier. I've replaced the rotor, too, mainly because the original was damaged (the screws holding the starter clutch had sheared off and made a mess of things), and it is still magnetic, although I can't vouch for how much. The battery was also installed new, it's not now, but it hasn't been used very much.

My issue is the low voltage. 12.8 VDC isn't going to do much more than maintain the battery, it won't really charge it. That's been covered here and elsewhere, I do understand that it really is more of a maintenance system than charging system. Using the starter over and over pulls the battery down enough to where that weak charging system can't maintain it any longer, and then it's time to go back home and put the bike on a charger to bring the battery back up. I'd like it to do better, and I'd ride the bike more and further if I trusted the charging system would keep that battery topped off, which I don't.

So - that's my long winded response!

I'm guessing the 99-101 for the 350/360 either won't physically fit, or it's wired differently?

Very different

Okay, thanks....

Randy, goofy question -- is there a service out there that 'recharges' rotors? I actually did make contact with a magnet manufacturer here in Maryland, and they were intrigued by the idea, but I think they would normally be doing it to a) much larger units, or b) a much larger quantity than just a single rotor. In my case it never went any further than a general inquiry and informal discussion.

The rotor is one of the things that I did change in my system - if you try to track down the earlier rotor (I think it's the one without the 'F' stamped on it), it supposedly has a higher magnetism than the later ones. But as you say, here we are over 50 years later, and who knows how much of the original magnetic charge is still intact in these rotors (even an NOS unit), how have they been stored during this time, have they been stored next to each other (which I think would reduce their charge). Lots of variables!
