I am new to riding, how much vibration does the Ultra have at 60-75 mph? Took the bike back to the dealer and he stated that he tightened all spokes and checked the balance on bothe tires. He also checked shock and tire pressure and stated the drive belt was a little too tight. Said there was a differance, but also said I should ride it to see if it was better. Before my teeth would chatter, now they don't. I still feel vibration on the right foot pad, and only a slight chatter now. What do you think?
