Also, there is a bit of carbon build up on the spark plug, it was brand new no more than 10 miles ago. Could the potential problem's that you have listed have that sort of effect on the plug or do you think I would be looking at something else as well?

The p/valve looked quite cankery as well, was the exhaust coked up?

I'm not sure, is the p/valve where the exhaust fastens on to?

I haven't checked the exhaust but I'm presuming that it's just as mucky. I didn't think that would effect anything?

So, I think I'm just going to go with the option of rebuilding the top end. That way at least I know exactly where I am with the maintenance of the bike. I have a couple of questions though.

1) What exactly is required to rebuild the top end and how much time should I expect it to take?

2) Can I do all of the work myself or will I need a mechanics assistance?

3) How much should it cost?

Thanks for the help guy's!

Best to ring LT, with all the bits in front of you, they will know what you need.

Thanks.
