oliccm Posted August 20, 2011 Report Share Posted August 20, 2011 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 Quote Link to comment Share on other sites More sharing options...

Cheers Hi,sounds like the main bearings have gone allowing the crankshaft to move from it's axis causing the gear on the primery drive to wrongly mesh onto the clutch and the piston to knock on the barrel and or head.The smoke will be the gear oil as it gets warm and thin enough to be sucked through the gearbox side main bearing/seal and then burnt in the combustion chamber.The main bearings on a gasgas incorporate the seal .

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?
