The Ultra is under powerd riding two up. I had to add a set of cams to help it along. Who the hell needs a ambient temp gauge, change it to oil temp if you need to plug a whole with a gauge.
How about putting on an aluminum 90 degree valve stem that the rider can actually use to fill the tire without contorting themselves in 14 different ways to get around the brake rotors!!??!! :S
Lots of good suggestions here. My favorites:
On board suspension adjustment
On board windshield adjustment
More power / Less heat
Balanced AND rubber mounted engines
Useable tire valves Solid Billet Motorcycle Tire Valves! 82° Stem! Bought these, great product
Better sound system
Comfortable seat
I'm sure there are more, most of the suggestions are good ones, good thread idea!
With respect and a chuckle-- The BMW Motorrad Centre has the top 5 of what your wishing for.. ;-)
