Hello Robert.
I have almost 3 oz on my rear wheel and 1/8 oz on the front with Metzlers on both cast wheels. Smooth as silk. I do get some minor engine vibration at around the 3500 rpm mark that I can almost dial out with Carb balance. No other vibes.
You bike should be as smooth as silk. If the dealer says it is normal, test drive another to see if the vibes are similar.
