Hi FLH59,
I'm the happy owner of an '07 Superglide (96 engine).
Happy because finally, after waiting 20 years, got a Harley under my Ass.
All it took was for my wife to leave home !!!
But that's another story.
What I can tell you is this,
I went to the local Harley dealer "open house" event a few weeks ago
in Kenniwick, Wa. and test rode an "08 Softtail Custom (96b engine).
As I was riding away from the dealership I literally looked down to see
if I was in fact on a Harley.
The diff in vibration is incredible between the balanced and unbalanced engine.
I recently read a post on another fourm about someone having bought a
hondayamasaki , or something , and describing it as a Harley on water.
I would use that same description of the 96 vs the 96b engine !
