Right then dpreece, I take it you are new to this forum lark, otherwise you'd know that the New Members section is for people wanting to join the forum, to take the opportunity to introduce themselves, where they're from, what sort of bike they have etc, once they've done that, they then go on to find the particular section they need, to explain the problem they are having with their bike, which in your case would be the 'Yamaha Workshop' section.

Now then once you posted in the 'Yamaha Workshop' section with your problem, you then need to tell us, what you've actually done yourself, to try and rectify your problem, so somebody with the knowledge of your bike can then think of trying something that maybe you've missed.

If by someway you were a bit of a techniphobe, and new nothing about bikes and therefore unable to check yourself ,rather than can't be arsed to check what might be at fault, we'd know because you would have told us in the New Members section, get my drift?

Oh and by the way it's 'isn't' not 'aint'

be nice if you did a newbie post telling us about you 1st than seeking help. but anyways welcome tell us more about yourself
