I just got my 2013 ST (bought new, now has 53,000 miles on it) back from the dealer’s shop. I replaced the two front tires and had them balanced before taking it to the dealer. They did oil change, replaced purge valve, air filter, spark plugs, front brakes & rear tire (with Yokohama 205/55R15). They also did a laser alignment and said everything was fine......except when they test drove it, that the front tires needed balancing, and it vibrates the handlebars.
Since I had just paid for someone to install & balance the new front tires, I said I would take care of it. Riding it home, it shook pretty bad and also pulled slightly to the right if you took your hands off. I had it static & dynamic balanced at the tire dealer where I got my tires. It still vibrates the handlebars and still pulls to the right.

My question: After doing all of the above, what would cause the handlebars shaking and the pulling to the right? Tires, balancing or/and alignment?
Thanks for any help!
