as Larry says , Birds are supposed to sit lower in rear , look like they go 'uphill'....personally I didnt like that stance ,so I changed mine , but rather than raising the rear (which many did in thelate 60s ,early 70s) I lowered my front...cut 1 full coi off the front springs, lowered it +- 1 inch...I get many compliments on the stance and I like it. see my pics
