I've been reading up on everyone's feedback about burnt stators, the undersized R/R, and long wait times for warranty work. Here is one solution that would get you back on the road sooner and/or prevent you from being stranded by the more than probable likelihood of stator failure. I emailed Ricks Motorsport Electrics with the particulars of the 1125 rotax stator. This was their response: We can definitely rebuild this for you if you send it in. Cost will be $145 and it will be in house about 5-7 business days. Please be sure to include a note with your name, address, phone number, year/make/model and that you're sending it in for rebuild. Thanks again! Amanda Shaw PR & Marketing Coordinator Rick's Motorsport Electrics, Inc. 30 Owens Ct. #2 Hampstead, NH 03841 603-329-9901 www.ricksmotorsportelectrics.com After you send in your stator, I'd venture over to this website: http://www.easternbeaver.com/Main/Elec__Products/C onnectors/R_R_Connectors/r_r_connectors.html This is the MosFet R/R that has been discussed as THE part to get. This website also has the weatherproof connectors for the FH012 regulator so your retrofit will look like a factory connection instead of a hack job. | ||

According to Dealership and Buddy that works at PDC, new stators should be going out early next week. | ||
| Tpoppa |
New stators as in another batch, or as in a new design? | ||
| Ezblast |
Good question! | ||

Unique_id - Makes you wonder if that is better? A 'higher break even point' sounds like more RPM's to me. | ||
| Unique_id |
Yea I agree Dan; at least it is cheaper than buying one through HD (I think), if one wanted a spare or to get one re-wound. | ||
| Dannybuell |
I have more confidence in HD than most of the people over here. They will make it right. I think that HD is struggling with vendors namely Rotax and electrical. HD should not be out of the picture in anybody's mind unless you are out of warranty. If you are not out of warranty and have an extra $500.00 buy an extended warranty and leave the worry to them. | ||

I have more confidence in HD than most of the people over here. Good for you LOL Personally, I'm buying a few strategic spares in so the dealer can have some time to get bits that fail (and are on backorder) and using those parts when they finally arrive to re-stock my spares. I'd be "OK" with buying another "different" stator and R/R "just in case" and if the original fails I'll be back on the road in no time even though I'll be waiting for the parts to re-stock. Erik Buell Racing seem to be ramping up their parts supply slowly, so maybe (at some point) we'll be able to get most of the parts from them... who knows? | ||

So finally something that makes us 2008 owners special  Our underweight stators. | ||
| Cataract2 |
Our underweight stators. That don't fail. | ||

Rick's is a VERY well known vendor that has helped out many VFR owners who have burnt out their stators. $500 bucks for a 2008 cover? It is a nice alternative but not cost effective. I'll pay for a stator that I'll get in hand within a week vs. playing tonsil hockey with a less than enthusiastic parts counter person. You know the saying, 'a bike on the road is worth more than 2 in the shop'. Letting a bike sit for over 2 weeks at a dealer in the prime of riding season is a real shame. The R/R upgrade is something I have yet to see anyone associated with HD even mention as a possible improvement. Buell did not building these things with unobtanium, they made these to ultimately make a profit. This R/R modification is a much more efficient electrical component and is less than 1/3rd the cost of buying a 08' stator and rotor for your bike. Didn't Erik goto school to become an EE? Or am I mistaken? | ||
| Dktechguy112 |
megadeus, The item on Ebr's website is not just the stator, its the stator, rotor and cover for $450. | ||
| Dannybuell |
those are 08's. what do you think they are using? | ||
| Megadeus |
You sure that Erik Buell Racing is selling the 08' rotor with that cover? The Erik Buell Racing listing doesn't definitely say that it comes with a rotor, just that the associated rotor happens to be a bit lighter. | ||

So are we seeing more failures now that the Summer heat is upon us? Why not last summer as its a MY 2009 problem and lots of these bikes should have one summer under their belt? Is it a mileage induced issue combined with higher operating temps during summer heat? | ||

>>>>Didn't Erik goto school to become an EE? Or am I mistaken? No he did not, you are mistaken. | ||
| Dannybuell |
Mechanical Eng - http://www.motorcycle.com/events/erik-buell-interv iew-65996.html Let me clarify, What I meant to say is what are they doing with the 09 ones they are replacing those 08's with? (Message edited by dannybuell on July 17, 2010) | ||
| Fresnobuell |
Probably sending them back to HD to pay for some of the bill for the batch of '08 stators they are selling on the site. Just a guess. | ||
| Tibman260 |
Why on Earth are you guys buying a new R/R? The problem is the stator, not the voltage regulator. | ||
| Megadeus |
The oem R/R can't sufficiently shed the heat created by the 09' stator but has no issues with the 08' stator. My train of thought is that the OEM shunt style R/R can be improved on so one can utilize the higher output stator reliably. The MosFet Style R/R effectively shuts down stator circuits when the current load is not high keeping the stator circuits from overheating. Y'all do realize the OEM shunt style alternator is running balls to the wall 100% capacity for the given RPM? With minimal loads being present, the output current not being consumed is turned into heat. The oem R/R can't get rid of the heat quickly enough and your stator goes sizzle Mcgriddle. | ||
| Dannybuell |
Megadeus - "Y'all do realize..." Are there two different styles of alternators, a shunt style and Mosfet? I DNK anything please explain. Fresnobuell - I thought electrical parts were not returnable. Now they are swapping parts? IDK. (Message edited by dannybuell on July 18, 2010) | ||
| Megadeus |
Mosfet Style = Control and efficiency  Shunt Style = Heat Dump and cheap to produce (mind you this diagram doesn't show a the regulator, just the rectifier but you can clearly see the difference)  Danny, if your understanding schematics is not so hot, then I suggest you take you time some time googling the two subjects instead of going why why why... | ||
| Dannybuell |
Megadeus - Can you assemble a kit to do this? I'll help with the DIY Instructions, if you kan git meat 2 nersand itll b fin. | ||

For the record, you *could* build a shunt regulator with a MOSFET. You can think of a MOSFET as an electronic relay, that is controlled by voltage with no current draw. They can handle massive amounts of current because you can run them all on, or all off. Power is heat, and power is volts times amps. So if you can get high volts but almost no amps (open switch) you dissipate almost no power (no heat). Then flop it to all on and have high amps but almost no volts, again you have almost no power dissipated (no heat). They are amazing little devices... I wish I had started playing with them 20 years ago. | ||

I perused the MOSFET wiki entry. I'm afraid that I'd need several weeks alone in a library to really understand it, but it makes the point that MOSFET devices work worse as temperature increases. Might one hack be to simply move the RR to a cooler place on the bike? http://en.wikipedia.org/wiki/MOSFET | ||

Hello - found this thread while searching for something else: I hope my interjection is helpful - certainly well-intended for my part. To clarify, the MOSFET regulators, like the SCR types are STILL Shunt operation; the lower diagram shown in the post above actually shows no shunt, just a rectifier; in an SCR shunt, the SCR's are normally connected in parallel across the rectifier diodes. A MOSFET R/R will not protect a stator any more than an SCR will - it still affects the stator in exactly the same way, not reducing the current load on it at all. The main advanatage of the MOSFET R/R is as a replacement where the predominant failure is of the R/R itself - the benefit of the MOSFET is that when in shunt, it dissipates far less power - it is the generated heat of the SCR that kills those units. If this is a stator reliability issue, then a better solution would be to go to a Series Regulator (Series Regulator goes 'open' vs a Shunt which 'shorts') Such a device is the Compufire 55402 - that will have a significant (beneficial!)effect on the stator current and thus the stator will run much cooler. I have written threads on quite a few forums as an advocate for replacement of SCR with MOSFET R/R - but these are for those who suffer chronic R/R failure. http://www.triumphrat.net/speed-triple-forum/10450 4-charging-system-diagnostics-rectifier-regulator- upgrade.html (I have no affiliation nor financial gain associated with any of the products mentioned) p.s. Megadeus - I'd appreciate if you could download that Shindengen image and host it directly yourself, rather than linking from my Photbucket account - my bandwidth gets taxed enough. Appreciated!
