Kev will be along soon to give you more advice, but I would try to raise the CO still in increments of 5 until things improve. First and foremost, make sure your tickover or idleing speed is set to be between 1450 and 1550 rpm at least to avoid the bike to starve at close throttle, which is one of the main reason for surging. Also adjust your chain slack if excessive.

Good luck
