More power Mr. Scott

[81xsproject]

I was just reading over on kzr and somebody was telling somebody else that they could hove somebody rewind a bad stator... Anyway, I remember at one time an eleven member was talking about trying to over wind thier stator to get more power out of it. Did anything come of it? Does anyone else remember this? Am I just imagining this? Wait, were am I?

81xsproject;

You're not imagining this. I am that person. Another 'project' I haven't gotten around to yet! When I have my workshop put back together (due to house fire) I'll get around to it and report the outcome.

[81xsproject]

I didn't hear about your fire. That sucks. I figured it was you the electrical guru but wasn't sure. Good luck putting your house back together.

[DiverRay]

Randy, you didn't let us know about the fire. I hope it wasn't an ELECTRICAL fire
Seriously, I hope no one was hurt, and you can get things back together soon.

Hey Jessie,

I also remember someone posting a message about a company offering to rewind the ALT's, I think it was Tod/TRBIG, but not sureA? I think their turn around time was not very good either!

BTW, I've editted your thread, I'll allow your youth to be an Xcuse for your StarTrek FauxPaux, but Mr. Spock was the scientist that provided the analysis for Capt. Kirk, but it was SCOTTY that was always being asked for more power!!

Ya, we'll call it youth, TC

BTW, I've editted your thread,

Good thing you fixed that, T.C. I would have been all over his @ss had I seen something amiss concerning Star Trek.
Randy... you never mentioned anything about a fire. Not that we could have done anything anyway, but... well, you know...

If one would add more windings, would a smaller wire diameter affect anything ( so you would have room for more wire) within reason, and would you say... 10% more wire windings give 10% more amps? What if one could do some modification to get a car alt. to fit...would the voltage reg. handle the amps, say maybe 60 amps? Or would you FRY stuff? I have, fairing,running lights, hard bags, and trunk. I took several lights out of the bags and trunk and still have to charge the batt now and then. I need more power. Thought this could be a winter project!!!

Thanks for the good wishes, fellas.

Had a fire back in Jan, been 8 months of contractor meetings, insurance adjusters, renting a house, moving, re-building and moving again and my workshop is, of course, the last thing to get done. In my bizarro world, somehow curtains and paint take precedence over my needs? Well, I did find time to make the W.V. rally, in the middle of the whole mess! Every man has his limitations, after all.

Luckily, no one was home when it happened (and NO, it was not electrical) a neighbors' flue sparked up the deck! I was fortunate to have a humongous insurance policy. Don't even THINK that!

As for the re-wind, I was going for adding about 10% to the field coil windings to boost the alt. output, there's not much that can be done with the stator (no room for more windings). Electrically speaking, it's a bit of robbing peter to pay paul, but if I can get the idle voltage up 1 or 2 volts, That would solve most of the XS's charging shortcomings. As most of you know, we don't have a REAL regulator, it's more of a cutoff circuit that limits the max voltage. I'm just going for a better than 12v idle output.

Film at 11.

BTW, 81xsproject, for you Star Trek blunder, you are banned from Valhalla. Too bad, being so close to Guru. Of course, you can redeem yourself at the next rally by providing a sacrifice. Buy the beer!

[randy]

red bandit,

There IS room on the field coil for about 10% more windings. Car alernator? I'd rather begin another moon project!

[Pat Kelly]

I was sitting on the toi..........in the study and thinking about the car alternator idea (several years ago).
If you removed the stator cover and all the charging stuff inside, installed a pulley to that end of the crankshaft, and had that pulley turn a belt that went up and back to an automotive alternator/regulator that was mounted behind the cylinders on a custom fabricated (who's got that new CNC machine?) mounting bracket, then wired to the bike.
New alt/reg units are very small nowadays.
People make room for turbos and blowers, why not something useful?

[red bandit]

With the lights I have, I don't think 10% will be enough. That's why I was thinking of a car alt. But I was thinking of keeping it under the original side cover. Get ride of the housing, just keep the guts. Yeah there will be some machining, I'm a machinist. Not an electrical guru. That's why I would need your electrical knowledge. With the newer smaller alts... Just thought it might be possible. Will have to check junk yards this winter. Definitely open for ideas/help.

LED?

Have you considered the LED mods.

Seems TC and others have had good luck with em and from the pics looks to be a "bright" idea.

[red bandit]

Yeah, thought about it, (LED) till I priced it out....15 lights gets pricey. Not to say moding an alt won't be. Time too. I guess I like to make things.

I like the idea of rewinding the current alternator. You could redesign it like a car alternator if there was room for diodes. Another possibility would be to build an adaptor plate between the crankcase and the cover providing more room. That might look a little wierd. I have a spare alternator with bad external wiring. If I knew what I was doing, with a little help I could do it.
