Need some more info, is it an X11 or X12, are you running boosted or blinky?
Either way you'll need to ditch the 100t spur and fit an 88 for boosted and something smaller 78-80 for blinky.
As a guide you will be looking to get a rollout around 45mm/rev for boosted and 65mm/rev for blinky and work up from there.
