I thought I would add pics to a pretty simple mod. I read alot of people changing the spring with out removing the tire.. First jack up the bike high enough to work under, I was on the third saftey of my Craftman, I went ahead and removed the rear tire so I could get to the rear shock mount (radial arm). First remove the lock nut on the pre-load adjuster, Second loosen the adjuster until it comes off, mine didnt even spring at all (pucker factor was about an

but no worries, once the spring is loose take the thin c-clip off the rear of the housing then remove the rear shock mounting bolt, the metal plate, plastic bushing and spring will slide right out the back.
Then just reverse order and done.
Since I now have a 1100LB spring I adusted the pre-load all the way out and the rebound at 10 clicks(will be different for different riders)
Plus the bike sits about 3/4 to 1" lower
