Question about 2002 kawasaki VN 1500 Vulcan Classic
It does not look like you have hydraulic lifters, but there are separate adjusters between the valves and the rockers. Depending on the amount/frequency of the clatter you either have bad valve lash adjusters or you have bad cam chain tensioners that are not holding the adjuster in place. The valve lash adjusters would cause a high pitched tick or click. If several are bad it sounds like marbles bouncing and rattling around inside your motor. A simple check of the valve tolerances should tell if the lash adjusters are bad.
If the cam tensioners go bad then you get a clatter sound . Two bad tensioners can be quite noisy. If the tensioners are manually adjusted you may be able to turn the motor to top dead center on the combustion stroke, loosen the tensioner bolt and retighten the bolt to get rid of the clatter sound on that cylinder. If it is a self adjusting cam chain tensioner you will have to replace the tensioner to stop the adjuster from clattering.

Could very well be does noise diminish when it warms up ?? i have a 1981 classic and never had a problem apart from exhausts rusting out ,I would be inclined to take covers off and have a look as the fault could be a valve seat worn ,wornor a worn camshaft and without having a nice little strip and play its too difficult to put a finger on it
