It's the one on the bottom of the page ? That's the one i bought. is the one you received smaller than the Duke's stock one. i could only use one bolt to mount it cause the spacing is different. Maybe my new one is just wired incorrectly?

Yes, it is a bit smaller than the stock one. Sounds like yours didn't get wired correctly.

I'll be trying mine today and let you know how it goes.

OK, and if you could, pleaselet me know what your voltage is across the battery when running. Mine gets to about 14 volts.

Happy dance!!!!!

Works beautifully.

I have 3 Chinese RR, each with their own issue, this one works perfectly.

Previous RR:
Idle, no fan: 12.8-13.8v (depends on the day, literally)
Rev 3k, no fan: 12.8-13.3v
Rev 4k, no fan: 12.8-13.1v
Fan drops voltage to 12.4 in all situations above


OMP RR (took videos and will try to post soon):
FAN OFF:
1000rpm idle voltage: 14.5v
3k rpm voltage: 14.7v
4k rpm: not tested

FAN ON:
1000rpm idle: 12.6v (woohoo!!)
2k rpm: 13v (woohoo!!)
2800 rpm: 13.3v (woohoo!!)
4k: not tested, but voltage was still climbing.

Finally!! A RR that can handle the power consumption of the fan!! Had one before (another Chinese one) that would go to 16v, but would overheat after 5-10 minutes and shut off.

Joe - Check yours w/fan on. That's when they're under load. Under no/minimal load, many of the Chinese ones can go around 14.4-7v.

Congratulations, yoster. What wattage headlights are you running? Are you running 1 or 2?

[yoster]

Thanks! Running two 35w bulbs; upgraded from the stock 25w.

Ok got some videos up. Crummy quality; taken on my blackberry, but should serve the purpose!

Starting up:


Idle after scooter warmed up:


Radiator fan on:

Fantastic!! Now that is a good charging system. Good job.

Scooter off, i get about 12.6v. across the battery.
Scooter on, idling, I'm getting 13.5-13.6v with the fan on. Same with fan off.... this is the same in idle and at higher RPMs, doesn't really make a difference. It may go up a .1 or so at higher RPMs, but really nothing.

Went on an hour long ride yesterday, without a hitch....

Cool, well just keep an eye on it. The fact that it doesn't increase as you rev up either means that the RR is already at its capacity when you're idling or one of the internal circuits isn't functioning correctly allowing it to go to 14-15v. My original RR would do the same however in warmer months it would overheat (the RR) and the voltage would slowly go down as I rode it. I had to charge it about once every 4 trips to and from work.

Sounds like your stock RR may be a bit more robust than my original, and the three replacements I purchased afterwards until I finally went with the OMP lol.

I pretty much have the Same Results as Yoster when it come to the OMP RR. My only difference is that I RUN HIDs. And I have a Switch on one as I turn it off during the day when I do not need as much light but do need more Juice to supply Cooling fan. At night when it is cooler the Cooling fan not coming on as much I then run both Headlights. I voltage pretty much stays at 14.1 volt except when the fan kicks in then it will drop down to about 13.5 before the fan kicks off.

In hindsight I suppose I could have just picked up a used RR off a Goldwing GL1100 on eBay for 40 or so bucks, re-wire it, and be done with it. Oh well, live and learn!
