[QUOTE="mla2k4mla2k4, post: 175423, member: 2009"] Hi everyone, Im going abit mad, I was at my local track on Saturday and for the first time ever I noticed that there was a considerable flow of air out of the breather pipe coming from the camshaft cover (about as hard as you could blow through the pipe if you tried only continuous) so my question is, is this normal?? I've never noticed anything like this before. My mind is torn between the optimistic dont worry the camshafts are spinning that must be the cause.... and terrible thoughts of cracked heads and leaking valves (seals?) other notable points: the air is not smokey, or particularly warm or hot another breather is present that goes to the frame - this is also pressurised the same Can anyone with a similar bike check this for me?? or anyone with similar experiences? Thanks in advance for the help I dont have anyone i can ask locally edit: The bike is a 2003 yzf 450 - No mods [/QUOTE]
