Got a few questions, I am trying to set the sag on my 450 and was wondering do you guys set sag with the shock warm, meaning after a few laps or just do it in the garage in my spare time. Second, coming off a 2003 kx 250 2 smoke I felt the bike was a little twitchy in comparison... so when replacing the chain with a DID ERT gold I added a link to make the bike a little more stable. My question is will this affect the sag setting? Should I set it at 103mm and go? Or go back to the original chain length and start there? Any help would be appreciated.
