Being an impatient soul, I'm posting this here and in the knowledge vault -- all after many happy miles, my stator decided to retire over the weekend (amusing anecdotes and heartfelt than yous for assistance to follow later today -- short version, Buellers are the Best!) I seem to remember that there are aftermarket versions of these parts that yield a bit more juice than the stockers -- give extree lights and heated grips and all, I think I'd like to avail myself of the greater than stock power generation capabilities available can anyone help a burn-out (in both senses of the term) with sugggestions? thanks | ||
| Whodom |
Bomber, not sure about the aftermarket, but the 06 Buells have higher output alternators and IIRC will bolt on. | ||

Bomber; I went a-looking for a stator upgrade recently. Contacted Al, who didn't have any leads. Didn't find anything in the aftermarket via web searches either. If you dig up something interesting let me know. I'd like to upgrade the S2 as well. I'll be in the primary soon anyway. Henrik | ||
| Bomber |
Henrik -- wilco -- I'm on the hunt as we speak! | ||
| Lake_bueller |
What's the amp output on the stock stator? There are aftermarket parts available in 18amp & 22amp for the XL motor. | ||
| Whodom |
The 2006 XB alternator is 36 amp. | ||
| Henrik |
Lake; I think the output on my S2 is rated at 22 amps. I wouldn't mind getting into the low 30's, which I believe is where the newer stators are at. Henrik | ||
| Bomber |
stock is 22amps -- so far, an extensive search for higher output has found things only for big twins -- rumors abound about XB series fitting, but no definate word I'm lookin to get the MaDuece out of the E-Lab soonest -- I'll likely go with stock btw, failure mode was a magnet coming adrift from the rotor -- lots of intersting looking material in the primary lub ;-} | ||
| Mikej |
Save the lube and put it in a lava lamp, should be lots of good sparkly bits in there amongst the oily brass and copper dust. I know, I know, mission creep, oh well.... | ||
| Bomber |
OK gent's -- my research has shown few, if any, more powerfult generation plants for Sporties -- got off the phone with an indie shop whose opinion I value, who basically told me I'd be an idjit if I installed anything but OEM componants for stator, rotor and regulator. bummer, but there it is Mike -- now THAT'S an ider! hmmmmmmmmm . . . . .

That's what Al at American Sport Bike told me when I asked about aftermarket stators. He just happened to have a stock one for sale, too. I'd have thought something fishy was going on if it was anyone else that told me a stock stator was the way to go, and they just happened to have one to sell... but hey, it was Al. | ||
| Bomber |
s'trooth -- Al/Dave, couple others, I'll bank on their word | ||

Well, you've already established how far you can ride using a "total loss" ignition! If you wanna make it further than the 10 miles or so from Elkhart to Kiel, I think a new set of electron-packing gear is in order... rt Picture of Bomber loading the MaDeuce into the back of FMJ's pickup mercifully omitted here... | ||
| Whodom |
Bomber, Did you ask Al if the 06 components will fit? That would still be OEM. | ||
| Bluzm2 |
Keep in mind the voltage regulator. It's a shunt type, meaning that extra output has to go somewhere. That's what the cooling fins are for. If it's not going to the battery and accessories, it's going up as heat. A higher output stator may shorten the life of the regulator. Brad | ||
| Henrik |
Bill Bait if I ever saw some ... What would it take to install one of the newer 3-phase stators on a tuber? Would it be possible to just use 2 of the phases, or would that defeat the purpose? custom wound stator? Henrik | ||
| Bomber |
yikes, look what's started! Bluz -- the kits I found offering higher-output alternators also came with the non-shunt regulators (brain freeze on the correct title for these worthy devices) not talked to Al, as time is of the essence (I wanna go riding, now!)(not that Al would slow me down, he always gets swag to me PDQ, I'm just not in the mood to expeiement right now) . . . . . . Henrik's question, though, is of great interest to me, too -- now that I've been initiated into the brotherhood of stinky primary fluid, I know how easy it is to disassemble the thing -- wouldn't mind changing to a more energetic electrical generation substation this winter, if it turns out to be feasible | ||

I may get corrected here, Bomber, In my simple mind there is no reason to change the manufacturing dimmentions of the stator and rotor soo it stands to reason that an XB unit would fit. the switching gixmotronics that short the stator to ground to regulate the voltage and current are likely rated higher on the XB regulators, I like the idea of a 3 phase alternator and a disconnecting regulator VS a grounding one let the correction begin... | ||
| Bomber |
Dawg -- you may very well be right -- howsomeever, DaveS in Appleton got the stock units to me in A FREAKING DAY! Who sez buell parts are hard to get? on another note, the manual sez to not reuse the stator mounting bolts, as they have secret squirrel thread lock compound on em -- these bolts are kinda thin on the ground, tho -- anyone have a clue as to what kind of loctite I can use on the old ones? thanks, all, for the tremedous help! | ||
| Mikej |
Bomber, Just curious, but did your stator wires have any rubbing indication where they go under the saddle strap where some folks have found shorted wires? Any other indications of impending failure had a magnet not come loose? You are taking a few photos, right? | ||
| Bomber |
no other indications at all, til I went to start up Saturday Evening in Elkhart -- the wiring seemed intact (didn't test em, though), and unshorted -- given the lack of gut wrenching stick when I opened up the primary (just a lil unusual smell), I'm assuming the mag bashed the stator (you can see the tracks on the end of it), rendering it inoperable quickly, and without a grea tdeal of heat pics, aye! | ||
| Mikej |
(Note to self, hit the preview/post button instead of the little x button up in the corner if you don't want to loose the text you just typed....) Probably do you well to deburr/bevel/bend the saddle clamp some while you have it open as a preventative measure as noted in prior stator threads scattered about the KnowledgeVault someplace. | ||
| Road_thing |
no other indications at all, til I went to start up Saturday Evening in Elkhart We did give 'em a show in Elkhart, didn't we, Bomber? Two old guys, in matching jackets, pushing a dead Buell up and down the street...I left my helmet on in a vain stab at anonymity! rt | ||
| CJXB |
 I'd say more, but it really is crappy thing when you're bike breaks, so I'll let go !! Hope you get it up and running soon bomber !! | ||
| Bomber |
RT -- your a first class wingman, brother -- anytime, anywhere, I'm there! CEEJ -- you're being a lil nice, aincha? worrisome, it is located the last of the parts I need two shakes ago -- alll will be well by Saturday noon! | ||
| Firemanjim |
Course then the 2 dim bulbs managed to somehow rope me into running a tow service to somewhere outside of Chicago---- | ||
| Bomber |
FMJ -- if it took TWO dimbulbs to run a tow service to Chicago . . . . nah, wouldn't be neighborly ;-} Thanks again for give a boost to a stranger (I have it on good authority that they don't come more so than me) . . . I see you got to Nowhere Indiana safe and sound (and without RT running point er nuthin!) You're a good man, Jim -- thanks a million -- I owe ya one (or four) | ||
| Firemanjim |
The trip to Jim's was well worth it. I got to wrench on Snail's turbo Gix,fixed his oil leak/low oil pressure light issue and start the beast up. What a hoot!!Sure made Paul happy when we got him on the phone. And Jim B. found me some slippery bodywork for the Bonneville bike!! | ||
| Road_thing |
FMJ, Bomber: Thanks again for showing me around Appleton... ...TWICE!! rt  | ||

The XB stator is thicker than the tuber stator. On the XB it seems to be accounted for by machining the seat pilot back a little further, if I remember right. (the stator is closer to the case) The stator can't be replaced without replacing the voltage regulator too. You can't hook three phase power to a single phase converter. I suppose if you were the adventerous type you could feed the three phases through a simple bridge rectifier, then feed that unfiltered DC output to the stock regulator. I'm not sure how much the stock regulator would like that much power being fed through it though. The best bet would be to change both. From my experience the alternator on the Buell's is a series of design compromises. If you made the wiring heavy enough to handle all the power it COULD produce, it would be huge. In order to keep it reasonable, compromises are made with regards to wire size & number of wraps, so that it produces reasonable power at low rpm. Rewinding a stock unit with heavier gauge wire would increase its ability to carry more amps, but it would not make more power till higher rpm. At lower rpm it might not be enough to power all the accessories. Also, the magnets are heat affected. The hotter the motor gets, the less they produce. If you just wanted more power with a small change, the best bet might be not a custom stator (really expensive, trust me) but rather a new rotor. Changing the rotor to higher strength magnets that are less heat affected would raise the overall output of the system, and it wouldn't fall off as much when it was hot. I've built a few custom alternators at this point, and could talk well past the boredom point for most non-technical types. Sorry. |
