Hi Darren, not too experienced with either 13.5s or Novaks I'm afraid. From what I remember Novaks have quite high timing as standard, so change the timing boost to around 45 and slowly work up from there. Also you will need a higher rollout with a 13.5, maybe around 65mm per rev, but that's a guess. Maybe someone else could point you in the right direction there.
(I'm gonna have to have a word with Randy about the name though
)
