    Have no idea where to begin with it, but it needs sorting. There is no clutch lever, it works by engine speed and just snicking it in, bit like clutches changes on a bike. Problem is, it now rolls forward in gear when engine is off, and it shouldn’t. It’s invaluable to me especially at the minute so don’t want it to bugger up completely. It’s a Honda TRX420 (2008). Any help much appreciated.

    Cheers

    I am sure this is just like a big version of a C90 with a centrifugal clutch.

    Not sure not could be causing this fault, but it sounds like tired clutch springs to me. I could be way off beam, but its a thought

    I thought centrifugal but was told that only autos have them (its not auto, still has 6 gears – 5 forward and one reverse)

    I  am reasonably sure it is a centrifugal clutch. I googled the model and clutch problems but it didn’t seem to throw up many hits, just links to ones for sale on ebay!

    Is the oil fresh?

    Yeah oil is fresh(ish), I have always described it as centrifugal, easy fix then!
    Thanks Radar :)

    Hmmmm just been looking, the auto (electric shift) has centrifugal clutch, but as far as I can tell the manual shift (mine) has plates? So now I am confused! The reverse does use a ‘lever’ of sorts, the rear brake lever doubles as clutch lever for reverse. Think I’m gonna need to find a service manual!

    looks like it has 4 springs that attach to the clutch weight set, if 1 or more of them are stretched/broken then the weights will have nothing to stop them flying out and engaging the clutch even at tick over.
