Ok thanks for this, So can you help me in deciding what parts to order? I think i will get a piston and ring kit as well (Might as well do this at the same time) Which seals / bearings do i need to order? Cheers

Hi Guys, Im new here and just looking for some advice. I have a GAS GAS TXT PRO 2006, and there is a noise comming from the barrel when the bike is revved, its is a rattling noise, also once the bike is warm it begin to smoke constantly. Can anyone tell me what that is most likely to be? would it be piston an ring need replacing or a seal somewhere? I dont know any od the history of the bike before i got it, and i havnt done anything to it. Cheers
