Default Vibration

Got an 03 1200C with 36.000 miles. I don't ride it much any more as I am usually on my LoRider. Seems as though the Sportster has an excessive amount of vibration above 60 that has never been there before. Only thing I have done different is put on a set of B&H short shot exhaust, a Arlen Ness Big Sucker Stage ! Air Filter along with a Mikuni HRS 42 Carb. Have checked EVERYTHING I can think of with no luck getting rid of it. Any ideas?

Sounds like tires out of balance. Smoothed mine out at speed.

Make sure the nut that connects the seat to the handlebars is fastened securely.
