    i am experiencing an issue in the transmission or driveline/ final drive that I have not experienced until this last 4 day tour. The 1400 has almost 22,000 miles and in the last 1000 miles while on a trip I noticed that when I would shift down and come to a stop and then while taking off in first gear I’m noticing a clunk in the drive line as I let out the clutch like there is slop in the drive line. You only notice it when taking off in first gear after coming to a stop. I have never noticed this before and want to know if anyone else has experienced this or if this is a problem I need to have a shop look at.
    Feedback I’d appreciated.

    Get somebody to sit on the bike with it in first gear, with brake applied & let out the clutch (in other words reproduce the clunk) while you listen & observe.
    I would start at the rear then move forward & see if I could locate where the clunk is.
    If it's at the rear drive unit then I'd pull the wheel for a look see.

    Also be aware of new vibrations, the old bikes would get a vibe in the right foot peg when the u-joints were going bad.

    I will check this out. There is no vibration and I’m pretty sure the clunk Iswhen the slack in the in the drive shaft is taken up as the clutch is let out. I will check and post.

    This might sound silly but, have you checked the brake pads?.

    Recently I read a thread on a different forum where somebody was asking about how much play there should be in the buttons on a floating rotor, The buttons on his disk brakes were within tolerance, as specified in the service manual and by the manufacturer of the brake parts.

    Eventually the poster figured out the clunk was due to a worn brake pad moving around in the caliper.

    Well, I tried for about 20 minutes to replicate the clunk that I was hearing and could not make it happen. So I’m just going continue on

    Have you looked at the rear drive? When I got mine serviced and had the rear tire changed at 10,000 miles the dealer noticed the flexible coupling disk and spring drive rubber had not been lubricated at the factory and were acutally gunky and rusty. I took a long time to get them off. This could be causing a clunk.
