Congrats on the new bike. Yes, Harley has come a long way. Going from a 05 Electra Glide 88cu to a 16 Street glide 103 Ho was very noticeable but to my 18 Roadglide 107 was even more impressive.
No. I'll leave it alone. My '07 was stone stock, outside of the compensator. The 07 gave me 12 years of trouble free riding. I never took it back to the dealer, never. I expect the same thing from this bike. If I want a hotrod, I'll drag my Sportster out.
