So I picked up an '09 1125cr a week back, and am wondering if I should be putting a new VR on it. Basically, when I got it, I noticed the voltage dropping quite a bit into the 12s on the way home (mostly highway and backroads). I didn't really give it much thought as the bike always started and didn't give me any issues. The bike does have the updated EBR stator and drilled rotor (at least according to the PO). Now it's home, in a the big city. I volunteer as a moto-marshall in local bike races here and the first time I did it on the Buell, the voltage would keep dropping and dropping (we're talking ~20mph for extended periods) until it hit 11.9 and lit up. After, it would be slow to crank over, but still managed to start. I looked around the forum after that and ended up bypassing the installed harley "fix". Since then, voltage usually starts off at 13.9 to 14, and seem to hang out in the 13.3 to 13.7 range for most rides. It dips into the 12s if stopped and restarted while hot. A couple times, it dies after being restarted hot, but started up again easily and was fine. In any case, now I'm finding myself always keeping an eye on the voltage meter and worrying about it. Basically, I don't want to be constantly having this on my mind when I ride. Will installing one of those series VRs (SH847?) alleviate these issues? Do I need to re-check the stator? Am I at risk of killing the stator with the drilled rotor installed and stock VR? Thanks. edit: right.. should've posted to the sub-board. (Message edited by mazaev@gmail.com on August 20, 2016) | ||

Some on this board have went back to the standard factory wiring AFTER the stator/rotor (drilled) fix. Some have installed a series VR, others a shunt VR. Dig into the Knowledge Vault (Topics above) and see if you can find your answer there. I've got the '08, so my help to you is limited on this topic. There is a voltage monitor you can buy and mount. Basically several LED's, so it gives you a quick visual as you ride. Froggy has one. Maybe he will chime in and give you some more info. | ||

I have no idea if my 09 has a drilled rotor. However, after reading up on the issue, it seems to me either the drilled rotor, OR a series regulator will resolve stator and charging issues. It also seems, if I am understanding what I've been reading, that a series regulator would be a wise upgrade even if the rotor has been drilled. And the Harley"fix" can be tossed with either solution | ||

When I installed the updated stator and the drilled rotor I also installed a series VR and have piece of mind. | ||

If the stator fails on my 09 1125R, I will probably take the "belt and spenders" approach for modifications to prevent future failure: Aftermarket Series VR and Oil-Jet Rotor. (Message edited by Squish on August 20, 2016) | ||

a year ago i installed a new series VR and had a Ricks stator put in the bike. i was having trouble finding a reasonably priced rotor as this was when EBR has gone into receivership. i hoped that this would buy me a few years before i had to have rotor replaced. the bike ran at about 12.5 volts after warming up, but was not enough juice to run heated gear with out the battery light coming on so it was a chilly winter. fast forward to late July of this year....complete charging system failure. well, i bought another Ricks stator, and purchased the drilled rotor from EBR. both are installed and the bike runs at about 13.6 volts once warmed up. turns out the recent failure were some of the wiring from the stator to the VR outside of the case had worn through (not burned) and shorted everything out. the stator itself looks fine with no sign of burning up. either way, having all the know parts replaced to create a new, properly functioning system seems to be the way to go. |
