thumps Posted April 1, 2006 Report Share Posted April 1, 2006 Hi, I took the magneto of my gas gas 125 05 and white oily petroly stuff came out when i took it off.It smells like petrol and its like a creamy colour. What do you think this will be. Quote Link to comment Share on other sites More sharing options...
gasgas249uk Posted April 1, 2006 Report Share Posted April 1, 2006 (edited) The white petrol smelling creamy substance will be a mixture of your petrol / oil mixture and water. When whisked up they produce this creamy mixture. This is more likely to be the following (accepting the fact that your bike does not lose coolant water). Whats happening is that petrol / oil mixture is in your bottom end and is creaping past the mains seals into the flywheel cover. Water tends to condense inside engines and flywheel covers and sits sometimes in a small pudle at the bottom. They are then whisked together by the flywheel going around causing this substance. This shouldnt be a problem unless you find that your bike is running with a weak mixture. As well as petrol getting out , air may get back into your crank and cause your mixture to become weak. This will show itself in your bike reving high in idle or the bike continuing to rev higher than usual or idle and "hunt". The bike may also start to over heat and pink , where you wil hear a knocking noise coming from the top end of the engine as the fuel pre ignites. If this problem develops ou may ned to change you mains bearings as the slop in them i lifting the seal up and down allowing the petrol out and the air in. You will need to change the seals as well. I'm sure you wont have to do this , as its a newish bike. Good luck and drain that water out. Edited April 1, 2006 by gasgas249uk Quote Link to comment Share on other sites More sharing options...

lewis_gasgas Posted April 1, 2006 Report Share Posted April 1, 2006 Quite normal for the radiator to come on alot as thats its job the engine gets hot then it comes on . So it wont /shouldnt be over heating oh and just check your water/coolant in the radiator. Quote Link to comment Share on other sites More sharing options...
