Taking engine out burning oil

<< < (7/16) > >>

MarkCR750:
I've got one of those on mine, it looks horrible I keep meaning to remove it and fit a pipe that runs into a small catcher on the tail fairing, that said I've never know any oil to spit out, I take it you've checked the breather outlet is clear, million to one you introduced a blockage then you fitted the KN?, not very likely I know.

Yeah checked it no blockage the breather that comes out of crank case should go to oil tank yes . I've just had a pipe coming off it there is quiet a bit of oil comes out of it is that normal ??

that should  be the gearbox breather (the thin pipe) . i can safely assume you have left the top engine breather and the oil tank breather to just hang down behind the battery(these are the thicker pipes} I have seen cases that people have mistakenly joined the engine breather to the oil tank that thens pressurizes the oil tank ? forcing oil out on to the back wheel very naughty  ;)

First F2 I had to do was doing 350 miles to the pint of oil with just the stem to guide clearance excessive that went to 150 miles per pint when 1 stem seal failed(all on the exhaust side!)
