    Something is slipping as I pull away from a cold start.

    This is certainly take it to the dealer time, but wonder if anyone has ever had this difficult to describe problem.

    When I leave the bike for a while, then get on and pull away, if I'm anything but super gentle, something 'slips' in the drivetrain. It just does it once, and it only seems to do it after the bike has been left - example, it has done it every morning for the past few days.

    It doesn;t do it immediately every time, sometimes it's as I pull off, another time it did it at the roundabout about half a mile into my journey.

    It's hard to describe - it's like say if the sprocket was loose, or the chain was slipping. I've checked everything I can see, and adjusted the chain. No difference.

    I also wondered if it could be something to do with the clutch? Would make sense, if there was an issue with a plate sticking or something, you would get the little jolt as it worked itself free. Would explain why it only did it once, and only from cold.

    I'll book it into the dealers anyway, just curious to know if anyone else had ever had this happen.

    I wonder if this is related to your specific stalling issue?

    I only say that as your bike appears to exhibit the stalling issue more acutely that other reports I've seen.

    Does sound clutch-related to me too, hope you get it sorted.

    It's a strange one, could it be anything to do with the crush drive in the rear hub
    see if there feels to be a lot of movement between the hub and sprocket in the
    direction of travel there is always some as there are rubber buffers in there to
    take the shock out of the chain drive.

    Who would invent a vehicle that falls over when you stop?


    If you find a answer to your problem then please come back and post
    the answer as it will help others with the same problem.

    That's what I thought too. I had it up on the stand and adjusted the chain yesterday, gave it all a good wiggle around, everything seems to be tight.

    Also, as It's only got 3,500 miles on the clock too, I'd be surprised if the cush drives are going yet. I'd expect 15,000 miles out of those, minimum.

    Dazzor - it might be the clutch. I have maybe developed a slightly aggressive style of pulling away, to avoid the dreaded 'you know what' that everyone is fed up with me yapping about. Still doing it, by the way. I can rev through the cough 99% of the time, but if I'm not concentrating it will still stall on me.

    It's booked in for Thursday morning to have this latest problem looked at, I have asked them to look at the stalling as well, for what it's worth. Will let you all know what happens.

    OK, so just an update. It went back to the dealer to be checked.

    I have absolutely no idea what they were actually trying to say, but the diagnosis seemed to be that it's a common problem with Yamaha cross plane engines, that not enough oil gets to the clutch. Hmm. OK then.

    The solution, which they carried out, is to change the oil. Unfortunately, this seems to be incorrect, as it's still doing it.

    So, not sure where we go from here. I know a few of you don't like anyone complaining about the MT07, but I'm obviously going to have to take it back again and I'll post results in this thread.

    Mine does the same. Only when cold and only since its first service.
    Doesn't seem to cause any other problems so I have learned to live with it. Still got 20 months of warranty left so I am not bothered (Yet!)

    Fully synthetic oil normally causes that symptoms. Had that on some Honda 10 years ago.

    I would argue that full synth Jaso MA or MA2 oil normally DOES NOT cause that symptom. But Jaso MB oils would, as well as car oils. Regardless of synth, blend or mineral.

    Feel sorry for you. There's obviously an issue with your particular bike here. Just a thought? (And I don't know your situation..do you need bike daily to commute etc?)
    But Is it worth leaving bike at dealers over night and surely 1st thing in the morning they should be able to re-produce fault? In mean time borrow one of their bikes for a few days? (Pref another MT to feel the difference)
    They have a duty of care to sell you something that actually works. I would be starting to get a bit p$$t off by now and even thinking of going down the road of a replacement if its not sorted soon.
    As said above, Your clutch theory may hold a bit of water, what with the stalling issue? Good luck and hope you get it sorted
