I have been watching this thread for a while now, your oil problem is bugging me, as the XTX & R does not suffer this problem & they are basically all the same motor.

Can someone please take some photo's of the oil breather system for me, from the pipe that exits the motor & winds its way to the air box. Thanks.

I'm no eco-weenie, but I don't think it's a good idea to let the oil drop out on the floor/road/trail - even a small amount can polute a watercourse for example. Also, I'd not want any oil dribbling out in line with my rear tyre, just in case... x

What is the problem with emptying out the tube once in a while? I'd rather have the bung in so I can keep an eye on the ammount - if it is excessive, then I imagine you will need to top up the oil filler eventually, then ride to the dealer and get it sorted under warrenty!

Hey Stridey, Just noticed your post.

Due to the design of the air box, air will be sucked in through that tube and straight into the engine without being filtered. Not a good idea when you consider where the tube terminates.

The air box on a Z is a completely different design to the X and R which is why it cannot realy be modded in any way (bar the snorkel as JMo has done).

So Stridey, put your bung back in and live with it

Hi Folks,
just read this thread with interest as having now done about 2k miles I noticed that the oil drain pipe is full!! The mileage included some lengthy blasts along A and B roads and plenty of off-road sections in France.

Now I'm not the most gifted of mechanics and although the bike's running fine I assume I should drain the pipe and then re-check the oil??

Apologies for what is bound to be a daft question!

Worth draining the pipe every now and then, oil will collect in the airbox when the tube is full. Left mine a bit too long and filled a jam jar with oil (about 200ml I guess). That was after several thousand miles however.

Oil level does not drop significantly (even with the amount I collected) but worth checking the oil every now and then anyway.

Yip, just open the clip with a pair of pliers (move it up the pipe a inch) pull out the bung and the oil will drain out. When your done, stuff the bung in and replace the clip!

You'll be suprised how little oil is contained in the drain pipe (unless it fills right up to, and into the airbox!).

If your oil level was right then the simplest thing to do is to put the same amount of new oil into the bike as what has just come out!
