For $99, you could buy a few for spares.

Fernan:

From some other posts, it seems that the the BMW factory stator uses wire rated for maximum temperature of 180C and I really don't think this is up to the job.

If you could get your OEM unit rewound with 220C rated wire or perhaps even 240C rated wire I think that would be one good option, but many shops do not have these better grades of wire.

From personal conversations with the engineers at ElectroSport:
http://www.electrosport.com I have been told their wire is rated for 220C, and they have done other things to their design to reduce the heat load on the stator.



RM stator ( $99 USD) says they use 200C rated wire, better than stock, but probably not good enough to last "for ever"...
http://www.rmstator.com/en/motorcycl...stator-rm01040


Ricks offers a unit for $165 USD http://ricksmotorsportelectrics.com/
but does not specify the wire insulation rating ...

Not sure if it's true, but have heard some less than stellar feedback on the CompuFire unit,

Don't know about that. for me the Compufire really solved the issue.
for what it's worth:

the original stator with original R/R lasted 34,000 km

then the 1st rewind stator lasted 5,727 km with the orig R/R
the 2nd rewind stator lasted 4,750 km with the orig R/R
and the 3rd rewind stator (same man and same material than the first 2 rewound stators) is now over 20,000 km with the Compufire R/R and still doing strong....

btw no adverse effect either of the compufire R/R on the on-board electronics, computer etc...

conclusion?

C5 ...

Damn you're hard on stators...........
I have about 30,000 miles on my original unit and it's still working Ok,
but I expect I'm living on borrowed time.

I don't want to say the CompuFire is a poor unit as many of them as are out there it's likely there will be a few complaints.

I do want to install a series style R/R but would like to take some Oscilloscope measurements "just for drill" first. That's were the connectors from a dead R/R would come in really handy.... anybody?

Well I just pulled the trigger on a new BMW Generator and Compu-Fire series R/R after spending way to much time reading forums and doing other research. My personal opinion is this will give me the most reliable system. Time will tell....

I agree getting the very expensive bmw solution is likely the best ...longest lasting fix.

I opened up my bike (32k miles) a month or so ago to inspect my still functioning stator. It was black and very toast!!! Lumps of black crud all over it.

So I bought and installed the electrosport replacement as I plan again to take some long trips this coming summer. It went right in fine...and works great.

However I damaged my gasket and had an slow oil leak which I noticed after a ride on a warm day....result of being an old guy and my sore hip kept me from looking at how the gasket and the bottom bolt can together...not!!

so I got to open it up again. Evan with this short drive, I can see the overcoat epoxy(??) just becoming "milky" ...ie temperature impact.

I may be jumping to the wrong conclusion...but I think ANY aftermarket stator has a finite life in the f800 engine...just a matter of too much heat.

anyone have over 20k miles on an after market stator??

I had the battery fail 2 weeks ago, changed it, volts looked good and steady, then this week the regulator appears to have failed. 14V on my basic electricians voltmeter (whole numbers only, no decimals) but when I raise the revs it drops to 13 and when I hold it steady at around 4000 it drops to 12V.

Got a new reg, list price at the local dealer was $300. I know the parts woman, she said it'd been on the shelf since 2010, did it for $90.

Installed and it appears to have fixed things at first glance. Held steady 14V throughout rev range.

Next start up, it held 14V but occasionally showed 13V for a couple of seconds.

I priced the stator, none in stock, 6 weeks from Germany, and $1700 South Pacific Pesos ($AUS).

I'll take it for a run tomorrow and see how bad it is. If it's the stator I'll be buying a US one.

It does beggar belief with all the failure stories the dealer here has told me about (one local guy had his quit in the middle of the Canning Stock Route and according to the sales staff went full retard in the showroom on his return) that they don't have one in stock. As a dealer looking after their clients it's like they just don't give a fuck.

It is long past time to let BMW know the collective outlook of everyone experiencing failures and having to pay excessive $ for replacement

Finally got my Rick's Stator installed:





Overall, pretty easy to install. I started it up and everything seems fine. My heated grips haven't been getting very hot and I think it's due to my old stator not putting out enough power. Hopefully this fixes it. Haven't been able to take it out for a ride yet.

Lots more pics on my blog post:

That looks like a first class stator from Ricks. I like the way they put a light epoxy coating on the windings with good penetration.

My BMW generator showed up today and I got the Compufire r/r last week so I will be doing those things this weekend.
Last weekend's project was replacing my fork innards with the Traxxion kit.
After that - worry-free riding!
