Hi, Thanks to everyone who responded before. I ummed and ahhed about taking the bike back to the dealer and finally did it this morning (it wasn't revving passed about 7000 and I thought it may be limited). After changing the plugs, cleaning carbs etc (and basically giving the bike a thoroughly good service) they discovered a fault with the immobiliser starving the engine of juice. One quick fix later and the bike is now awesome! I can't believe I wasn't sure if anything was wrong before. So thanks to Thunderroad in Bridgend - I'd recommend their after sales. Tim
