    No such thing! Just keep the RPMs over 4,000.

    I agree with MarkF. Tried the Bosch 4418, but no real improvement.

    re thanks

    Thank you guys for letting me know. I have heard so many different stories about all kinds of things. A good throttle hand is also very important..

    So because I bought a oilhead and have learned to ride it so surging is not a problem I'm part of the reason that BMW still makes this bike? I'm part of the problem? What was I to do? Not buy the bike I wanted? Take it back to the dealer and complained about a problem I didn't have? Leave it in the garage instead of riding it and enjoying it? I don't think so...!

    Oh, great! Now I have to live with the guilt of causing another riders death just because I keep my RPM's over 4,000 and am happy with my oilhead. Please don't name me in your lawsuits.

    Question surging

    I agree with flash, sue em. I had a new GM truck that was a pile of junk, dealer coulcn't fix it, other people said they also had problems, they all must be junk. But there still is alot of them on the road maybe there was a different problem. Keep trying on my second oilhead neither one surged both completly stock.

    Thumbs up surging

    You used the word SOME, now why do SOME surge, SOME surge very little, SOME surge alot, and SOME not surge at all. I beleve BMW dealers must do as BMW tells them so they may be limited to what they can do. Much has been posted on what can be done to purge the surge, talk to other oilhead owners if they have few to no problems find out who is tuning there bikes. But I will agree that BMW has been a real stinker on this issue and the more people they hear from the better.

    plugs

    My 2 cents.

    On my 1997 R1100RT, purchased new, I used Autolite 3923 plugs and a twin max with excellent results for over 40K miles. Those plugs (yeh, they look cheap and cost almost nothing) always came out with a perfect brown color.

    I'm doing the same with my 99 R1100GS for the last 9k miles with the same results - surging is non-existent.

    As a follow up to my comment above, the Bosch 4418 plugs did not make any real difference by themselves. But, as Bart stated above, a good tuneup including a throttle sync (TwinMax) takes you a step closer to surge free.
    The final step that I took was to remove the CCP plug and remap the Motronic. This final step made the biggest difference and my '00 R1100RT now runs better than it ever has!

    surging

    Twin Max is an electronic device for synchronizing your throttle bodies. It is simple to use and very accurate. No real mechanical abilities necessary.

    A friend of mine used his on his R1150 GS, then had it in for some tires. He had the BMW tech check the synch and the tech said
    it was spot on.

    They are only about $80 and pay for themselves after a couple uses.
