Hi, I just checked my sag and I'm sitting @ 120mm. So I think it's best to pull the shock out to adjust the preload. From what I have read, the method for removal is: 1. remove the seat 2. loosen the lower subframe bolts and take the top bolt out. 3. take the shock bolts out and remove the shock through the top. Sounds simple enough, but it sure doesn't look that easy. Any other potential gotchas? Another question: if I need to take up 20mm of slack, any ideas much further I should compress the spring?
