Thanks for those replies,I checked for any kinked or loose hoses first,a friend of mine said that it sounds as though I might have disturbed something down by the throttle bodies that deals with the fuelling but I wouldn't have a clue about that,I'm really just a pads and oil/filters bloke ,when it comes to anything technical I'm lost.I really wish I hadn't done this job it's just that my local yamaha dealer charges so much I didn't even get a quote.Hindsight's a great thing ay? I've just sent for a disc workshop manual off e/bay so I'll have a look at the throttle bodies on there and see if I have disturbed something.
