Completed Tasks

June 2019

  • The tie-wraps on the rear fender broke, plastic welded it to see if that holds better
  • Reset the race sag to 97mm (static sag 45mm?) to see if that helps with the back end kicking out and the tank slappers
  • Put rear compression damping settings back to stock

May 2019

  • Tightened the chain a little
  • Backed off rear compression damping, slow = 1 click, fast = 10deg
