    Testing VR and stator health

    LOL, sorry. I've Googled a fair bit, but I'm still not clear on how to test the VR. I should mention that I'm running a Compufire 55150 after my stock VR started over-voltaging and blowing headlamps (since Jan 2014). Someone on Badweb had used this model VR as an upgrade before me, so I'm...

    Pretty sure my stator is going out.

    Old thread, but still relevant. I just wanted to point out that several folks have run the Compufire 55150 VR in place of the OEM Buell part. Far more reliable than the OEM part.

    Testing VR and stator health

    LOL alright, I don't know why my threads piss people off. I don't think I'm being offensive, but maybe I am. I really don't know. In any case, I don't have an agenda and I'm not trying to make enemies. This is just how I write forum posts. I'm sorry if I offended anyone. The thing is, my...

    Testing VR and stator health

    I am not asking you for your personal opinion of the nature of my question, so if you don't mind, stick with the topic and stop diluting the subject. Your response was absolutely useless!

    Testing VR and stator health

    I have tested the VR output. It's low... hence why the ECM is throwing a CEL and a code for low battery voltage. However, I just read something on CycleElectric's website: "A stator that is shorted to ground may still produce full AC voltage from pin to pin. The problem with this is the...

    Testing VR and stator health

    Actually, when I tested the bike I ran the current draw test while removing fuses from the fuse block. The heated grips do not cause a draw at all because the relay that energizes them is controlled by the ECM. The ECM senses when the engine is running and then energizes the auxiliary power...

    Testing VR and stator health

    Confirm stator replacement needed I have some confusing results from testing my stator (following the instructions in the Buell electrical diagnostic manual). The 1st check involves checking for continuity between ground and either of the stator leads. I have continuity between ground and...

    Testing VR and stator health

    I searched, but I didn't find the info I was looking for. I did however, find exactly what I was looking for in the '08 XB Electrical Diagnostics Manual on the BuellMods website.

    Testing VR and stator health

    Is there a definitive procedure to test the voltage regulator and the stator, separately? I made a 250 mile roundtrip journey on my '08 XB12Ss last weekend and the CEL came on the return trip. Pulled over at a gas station to fuel and feed, bike wouldn't start. Had to get jumped. Once...

    replacing regulator, polarity?

    FYI, avoid soldering if you can... the bike is a high vibration environment and soldered joints tend to fatigue and crack. This is why a mechanical crimp is the preferred method of connection - you'll be hard pressed to find soldered joints inline in a wire harness.

    DDFI-3 tuning with stock o2 sensor

    I think you need the Digital Technician software to update the actual firmware binary on the ECM, eg. BUEZD to BUE2D. I'm sure someone may have figured out how to do this, but the dealership can probably do this readily.

    Highway foot pegs

    I love the idea, but I could've told you that was going to be a high vibe situation from the design mounting the peg mounting plates directly to the engine. That isoplanar engine mounting system is designed to alleviate vibes on the frame and that would be the best structural member to add pegs...

    About to pull the trigger on an 1125CR

    It's ridiculous how cheap these machines can be purchased used for... my '09 1125CR is easily the most dialed motorcycle I have ever owned, absolutely no regrets with it whatsoever.

    AFV cylinder difference keeps running out of control.

    Perhaps your fuel maps have been altered and/or the exhaust/airflow upgrades require remapping to the point that the ECM is making note of it.

    Upgraded to SH647 Voltage Regulator. Glad I did.

    Nice upgrade. I have a tail eliminator on my CR, so I would probably opt to install the stator up front between the radiators, near the oil cooler, though. I don't think it would have any issues cooling itself mounted pretty much anywhere, however. My XB12 has the stator up front.

    Buell XB9SX Tyre Choice

    Bridgestone S21 works pretty good on my 1125CR at the moment, I wouldn't hesitate to run them on my XB12 either.

    Maybe buy '09 1125CR: questions

    At least you've got mountain biking going for you... I started riding in a very different environment (North Shore of Vancouver, BC, Canada) so the riding is very aggressive and requires good balance to cross many unavoidable wooden structures. The riding style has greatly improved my...

    difference between european and us maps

    The Euro maps have slightly more timing than the US maps due to improved fuel octane. That's about the only takeaway I have, but I believe the stock header pipe diameter is smaller on the Euro models as well.

    Long distance touring windshield option

    I once put a taller than stock flyscreen on my XB12Ss... I believe it was a Zero Gravity unit. It actually made the wind buffeting WORSE, so I ditched it and back to the stock flyscreen. I simply endure it.

    MegalogViewer & tuning fuel maps with a single wideband sensor

    Thanks, I must admit it did take some time to acquire all the data. Each cylinder took about 10-12 datalogs which I lumped into my morning and evening rides into work. The end result is definitely pretty satisfying. The only modifications I have to the engine are the K&N air filter and APH...
