    I've worked on live electrical circuits standing on an iso mat, wearing rubber electrical gloves with leather outers and a flash guard. I fully understand how to work live and the hazards of not.

    Nothing to do with doubting ones abilities, it's all about understanding the risk of accidental grounding. You say there is no risk, I say there is. Good luck in the future mon ami!!

    I too have worked on live equipment with the right safety gear.

    I would say in this case it is a calculated risk.

    Years ago, dad and I rewired the house without disconnecting the 120VAC 'cause mom wanted to watch TV. We pulled wire through rigid conduit and made connections on live circuits. I got nipped once, dad never got so much as a tingle. Of course, his profession was electrical engineer and he designed power plants for a living so he did know what he was doing.

    The spinning without engaging is usually the failure of the one way roller clutch in the starter drive.

    You can buy them

    Few boxer owners need new starters.

    Few boxer owners remove and rebuild their own OE starters.

    Few OE starters are damaged beyond repair.

    Most BMW boxer OE starters can be repaired to factory new condition, maybe even better.

    Parts for the OE starter are available.

    Replacing a repairable starter is a waste of money.

    I've said enough. :brow

    Ahh..Def, price what it costs to rebuild that starter using OEM parts and get back with me. Those that want to enjoy the mechanical satisfaction of repairing a starter, enjoy. I ride my bike everyday and the ability to buy a cheap replacement that bolted right in and continues to work years later makes sense for me.

    I greased mine, it was good, then it stuck again, greased it again......... eventually then I CLEANED it in detail, light lube never given issues since, over lubing with sticky grease is a bad idea:D

    Once you deduct the removal and refitting time (which you would spend with a new starter anway), the process of taking a starter apart, degreasing and relubing it is about 15 to 20 minutes. And you saved $200.00 by doing some basic maintenance...

    Thats good to know that they can be bought so cheaply, and that you have gotten great service life out of it.

    But from another perspective, I ride mine daily too, and sometimes I ride it to places that do not stock starters, cheap , expensive or otherwise, so I am glad to know what it takes to open the starter, clean it and make it work.

    A rebuild on the OE starter is difficult to judge unless we know the failure.

    Tbone, I fully understand your situation and applaud your decision to replace rather than rebuild.

    Finally, a carefully cleaned and repaired OE starter may be more reliable than the original.

    Ah, ah, ah. Did I mention that this thread is about fixing and maintaining a starter? It will probably interest a few people who think it is difficult and who like doing stuff themselve. :ear And if my starter fails 3 days away from home, I'll be glad I now know how to fix it in a rest area... ;-)

    Actually Euromotoelectrics carries a lot of Valeo (OEM) parts reasonably priced.

    So speaking of maintaining the OEM starter, what's the recommended lube to use after I take it apart and remove the grime?

    I will let other peoples chime in from their own experience. I elected to use a engine/tranny oil over grease. Grease will work in warmer areas but might be too thick in freezing temps... I don't hold the truth, so everyone's free to experiment and share. :D

    I used a very small amount of synthetic disc brake grease, very goey and high temp capable stuff.

    I would imagine anything thicker than 3n1 oil would be fine though, as long as its clean.
