I installed this upgrade a long while ago, but never had it adjusted correct. The trick is all linkage should be at 90°. I knew it was off, but it's hard to get my fingers in there to adjust it so I kept putting it off.
Finally, this past week during Christmas break, I made the time to correct this. WOW, WHAT A DIFFERENCE! Extremely better, positive shifting.
Today I rode into work wearing my new Goldtop jacket and shifting safe and sound.
