I have an 01 Ultra. I'm 155lbs..wife is about 116lbs. Bags/trunk are usually empty. What would be a good air pressure in the front and rear shocks. I've not checked them but just got the bike back from a total 'front to back' service and assume they checked it. Also, would lowering pressure lower the bike or just make it less stiff?. I'm also short with a 29 inseam. Although I can flat-foot, a little lower would be helpful.
