Hi.
What I've found from experience with static balancers that the bearings drag a bit, I removed the plastic dust seals & wash out all the old grease lube em with engine oil, it can make the difference between finding a heavy spot or not.
Is your bike tuned in any way, vibration might be from the motor, carbs set wrong, wrong jets etc, hope the crank ends not bent at flywheel side, seen a few bikes with bent crank ends from previous crash damage or ham fisted hammering to get a tight flywheel off.
Is this vibration at any particular speed? if so, does it still occur with no load (clutch in) etc?
