I have ordered an ‘03 Ultra and have the dealer looking into swapping out the 88 for the 103 from the SE Road King. I can get a credit for the 88 toward the 103. Since the motor was built by the factory this would be covered under the original warranty. I’ve heard the 103" has the potential to shake the living daylights out of the bike. Does any one have experience with a 103 motor in an Electra Glide? How does it ride out on the highway? Any thing else I should look out for?
