    Chasing down what I believe to be too much driveline lash on my new to me r1150.

    It really seems to clunk in the footpegs when transitioning on and off throttle. I cant recall if its been this bad since I got it, or if its been getting worse (only really had it for 200 miles.)

    No play in final drive, wheel rotates smoothly and without noise. Trans shifts fine, no particles in any oil. No noise with clutch in or out. Clutch spline play seems acceptable.

    I pulled the transmission fill plug and shone a light in there and noticed what I would characterize as a large amount of play. Unfortunately, I have no idea what I'm looking at in there.

    Here is a video of the play:



    This is in first gear. It seems to have play in all gears, will do a clunk at low speed or on the highway.

    What is this I'm looking at? Is this acceptable?

    Interesting idea, but I don't think it's a problem. If you want to check something, pull off your starter, tie off your clutch handle, and see if the clutch hub rotates on the input shaft. There's a good video around somewhere.

    Wonderful explanation, thanks! That makes a lot of sense to me.

    Seems like it's built in lash in the gearbox, and no matter how well you have the system working, abrupt on/off throttle changes are gonna clunk.

    Guess I gotta just get over it and learn to ride smoother lol.

    You think these are bad? Listen closely to a Harley shift. (From a mile away)

    Normal as stated. Be smooth with the throttle and clutch, the dry clutch is not to be slipped. Pre load the shifter and just fan the clutch, it will shift nice and smooth. If stopped in neutral it is normal to feed a little clutch to get into first. Takes a few miles to get acclimated to the bmw way.

    My biggest concern isn't the shifting action, it's the "clunk" I get in the footpegs when going on or off throttle, especially on the highway. If the play in the driveline Is typical, i'll just get over it

    Can those dog gears make a clunk or clang sound when starting from a dead stop?
