    Default Motorcycle UD 70 Chain vibration

    Hey Guys,

    I recently changed the chain sprocket of the tire because the last one had gone bad. The bike chain from than on has been vibrating - making a zrrrrr sound when I ride it. When ever I spin the tire by hand I can see ripples in the chain. Further, when the bike is clutch free a sound like (tuck) comes after every rotation completes.

    I used to ride around 80kmh previously but now when I am riding only on 60kmh.

    Can you guys tell from your experience?

    Check wheel alignment, sprockets and clean the chain with wd40 or petrol and apply oil.

    Portions of the chain have stretched. You need a new chain.

    Hey Guys
    Thanks for the replies.
    I checked the chain and sprockets. I think there is some issue with the wheel alignment. But chain and sprocket looks fine (chain is still oiled and new, and sharp edges on sprocket (back))
    Its been a week and the bike is running smooth (considering the roads of Karachi) I am driving am 80kmh.

    I think its fine and do not need a mechanic lookover at the moment as I am tight on budget

    Still thanks for the advice.
