hi All,

Any advice?....

My mc28 has approx 30,000 kms on it and for the last 1000kms or so it is lurching/lumpy and seems to knock abit when off the gas in most of the gears. Feels ok when on the revs, but just when rolling off or just with a little gas it feels strange.

Is this the start of the crank going? What would it feel like? how quickly do they deteriorate? I have stopped riding it out of paranoia! Last top end was 10,000 kms ago.

If it is on the way out, does the whole crank get replaced? Or the ends?

Thanks Mark
