    Out this morning and under hard acceleration the clutch seems to be slipping.....big time.

    It's OK under 4000 revs normal riding and road conditions, up hills etc but when you get above 5000 rpm accelerating to 80 - 90 mph the rev needle goes mad and you get sudden blasts of power.

    Seems odd when bike was fine last weekend and I've only done 1500 miles, tried adjusting the lever as I've changed to aftermarket, but no difference.

    Can it just want adjusting or anything more sinister ? Thought when its doing that under hard acceleration it's buggered ?

    Did this coincide with the change of lever by any chance?

    Hi Tricolore,

    How long have the non standard levers been fitted?
    i.e. are they a recent addition?

    If so, try refitting the standard levers mate.

    No, levers have been on 600 miles or more, the only difference Is I've been using more revs 6000 + and giving it a bit more welly....that's when you really notice it.

    Can't see a clutch slipping after 1500 miles, I often redline mine and clutch is perfect after 5000 miles. Have you changed engine oil? I'd suggest the above, try the stock levers again. It looks like a trip to the dealers is on the cards for warranty replacement

    I have never ridden one of these bikes so don't know how fast it revs up?:confused:
    You say you're using more revs and giving it more welly!!
    Couldn't be the tyre spinning up could it??
    Sudden blasts of power?
    Spinning then gripping???

    Don't think so guys, there's almost a loss of power over 5000 rpm. I've got it booked in, in a couple of weeks. I'll give it another blast at the weekend and give the dealer a better description.

    If you've had the tank off there might be a trapped or kinked hose?

    Check the lever is going all the way out, they have been known to stick a little....failing that you need to check the cable/lever adjustment at the clutch end of the cable...

    Well the bikes back after a whole new clutch being fitted. It would appear the supplying dealer when fitting the black engine cases didn't replace the clutch cable arm correctly, the clutch was slipping all the time but gradually just got worse, the clutch was completely burnt out after 1400 miles.

    I didn't notice anything until the last hundred miles or so but I bet I'll notice a huge difference now.

    All under warranty thanks to Triumph Birmingham
