    No sir,the sound reduces while riding.
    Will it require complete overhual to fix?
    Without opening the engine , it is hard to tell , because the condition of associated parts must also be evaluated....

    Good Luck.

    Please Copy this link into your browser and listen the sound of my karizma engine
    It is creating a thud thud sound on idle
    Some say it is crank bearing and requires engine overhaul.
    Some say crank is very strong of karizma it does not get damaged,it would be timing chain tensioner.
    Bike has done around 30-35 thousand kms
    One time half engine work,usha piston installed.
    Average 40+ and pickup everything is proper.
    No white smoke from exhaust.
    Please give your valuable inputs.

    Good that you have been able to isolate the problem to the source ie., the Carburetor...The air cut off valve at the side of carb can also cause this problem. To find out block the INSIDE of the vacuum hose coming into the Aircut off valve , and keep it connected. Better still replace air cut off valve diaphragm and install. Now check for problems...if problem continues then check for throttle slide being sticky or worn out .
    Good luck.

    My engine is creating dhud dhud sound on idle,which reduces when moving
    What could be culprit
    Some say timing chain tensioner,please tell how to check it.

    Some say it is crank bearing cost 10k complete overhaul.
