    Was wondering whether this is a common problem as mentioned in HOW for the SE?

    Going to Morocco in April and I'm taking the usual spare parts, was wondering if anyone has had a failure of the reg rec on there 950 Adv?

    Thanks

    Since then I realised R/Rs are expendable and should be replaced preventively.
    They seem to expire on all bikes, including Hondas. Good option is the new Shindengen, carried on Yamahas R6 as OEM part.
    Cheers.

    Not me (so far) but plenty others have lost an R/R.
    Apart from taking a spare (essential!) relocate your current one, or wrap your exhausts (even better) with exhaust wrap. Removing some heat in Morocco will do good to you too apart from your rear suspension and R/R :D
    Of course I assume temperatures of over 30C in Morocco in April, which might not be true.

    SE problem has been due to the mounting location near the exhaust pipes...


    Less reports of problems on the ADV due to cool mounting location. More problems of the connectors corroding. Keep them clean and protected and the RR should be fine.

    Now let's talk fuel pumps :eek1 :lol3

    My 9 year old regulator has about 48000 miles on it.

    So far, so good- knock on wood.

    I lost my R/R after about 3k miles on my 950 Adv. It was within 2 weeks after a hot ride in Death Valley where outside temps were 120 degrees. I don't think it was simply a coincidence. Excessive heat is the weakness of these bikes. I spent a lot of time rock crawling on this ride and my speeds were down for most of the ride. There wasjust not enough air circulation through my bike.

    My battery ended up going south not much later on too.

    Relocating the R/R is a plus. Bring extra seals for the slave cylinder. They are heat sensitive too.

    Yes people have fitted them, and I already know of at least one low mile failure. Chinese part.

    Get the proper Shindengen MOSFET for less money, it's OEM quality used on many top of the line Germand and Japanese bikes.

    With that installed I would not bother with carrying a spare.

    Apart from the wattage (of course) are all R/R interchangeable? That is to say, are all 3-phase bike generators similar in their voltage output?

    This isn't a definitive answer, but every bike generator I've ever measured has had an output of about 50-75 V AC, when open circuit.

    I think all RR do essentially the same job, if you can get it to physically fit, and if it can handle the wattage, I would expect them to be interchangeable. However I'm no expert so don't take my word for it!

    Pretty much, it’s all about the design. I.e. a two stator impute wouldn’t be ideal as the lc8 has three…and the peak voltage/amps may be too high for a less robust one.

    This is good to know. I have an R/R from a yamaha thunderace that might do the job as a spare.

    Look at the part numbers, might even be the same.

    I hope this is not a bad omen.

    I was adjusting the clutch and free play for the Rekluse on my bike today so it was idling with many cracks of the throttle to 5k+ rpm.

    This were pretty hot down below and under the set. Could not even touch the alarm box mounted under there.

    Well I had noticed that the volts were starting to climb while idling. Usually 14.4 volts while riding. It crept up to 16.8 volts before I shut it down. Went and got my hand volt meter and checked it against the one mounted on the bike and they both read the same but when I started it back up again and let it idle it seemed normal. Never did creep back up.

    I am getting ready for a trip in Laos next week and don't want to be stranded again. Last time I was in the mountains of Cambodia with a dead battery.

    So is this a sign of the VR going south?

    Lukas- has anyone developed a plug & play MOSFET unit for the LC8 yet- or do these still have to be pieced together?
