Just thought i would put this up, i did a search on the breather hoses from the tappet covers into the catch can in the airbox and apparently its a common problem for them to fail, mine lasted two years before they perished and decided to leak oil onto the exhaust, not a major problem but a pain in the arse when it happens while your riding, so just thought id let yas know,something to keep an eye on, cheers Mick
