Hey to all haven't had the chance to come on here in a while ,my bike was flying it until yesterday when after a short ride to the shops the top end is making a lot more noise like a metal clanging inside the head I am unemployed at the moment, so any help would be appreciated, basically I am wondering is it the big end bearing or a rebore needed,cheers jason

sounds bad Jason, you're going to have to take it apart for a good look at what's causing it

As above, the only way to tell is rip into it and see what the problem is, sounds like a broken ring or knackered piston from your description. Check your compression if you can before you take it apart, that might give you an idea of what's going on. Good luck mate.

Cheers lads a mate has one that seems to have the same problem he said he will come n take a look with me anyone got a link for a free PDF manual lost !manual
