pipes
[/quote]


They're tank pipes which I said before my bike doesn't have, you must have an older model.
The one Anutz has shown is one, and the other is on the left side of the engine buried somewhere?

[darrsi]

I presume 31 & 33

Pipes connect to both front bottom corners of the air box. If the pictures load in one of them you can see it between the idle adjuster screw and the clutch cable.  The pipes connect to a T piece and then join the pipe coming out the top of the gearbox. There is a black plastic connector that has a piece of sponge in it that acts as a firetrap to stop you setting fire to the oil in the engine if the bike backfires through the air box.

I presume 31 & 33

31 and the other pipes will be on airbox fiche.  Don't recognise 33 it might be the tank breather for the later models

[anutz]

Are you sure those 2 pipes either side of the air box are for crank case ventilation?

I thought they were for drainage?

I could swear a while ago i was told that somewhere on here as i asked what they were for...

i need to go look at my bike  :lol

[darrsi]

I'm confused now.
You're now saying air box pipes, not crankcase?

[anutz]

so there have been a few pipes mentioned...

Fuel Overflow
Fuel Breather
Crank Case Ventilation - i showed a pic of what i believe that to be, and the service manual only identifies one Crank Case Breather

The other 2 pipes that form a T coming from either side of the airbox and meet with a pipe from the gearbox i am not sure what they are for...i am sure they are just for venting the airbox and gearbox, not crankcase....

point is i am not aware of more than one crank case breather

clear as mud  :rolleyes

[Jules-C]

They connect the crankcase breather to the air box so any fumes/oil mist get sucked through the cylinders and burnt instead of dribbling out and leaving an oily puddle when you park the bike.

[anutz]

OK to update....on my bike...

Crankcase Breather connect from the top of the crankcase to the Air Box directly - no joins to anything else

A hose from either side of the airbox meets in the middle with a T and then the resultant single hose goes over the transmission to a cage on the center stand where it is held and pointed downwards to drain

I have no sign of any hoses connected anywhere else - this is a 2001 FZS 600

Not sure how other people are configured

[darrsi]

Soooooo, what am I checking, the hoses from the airbox to see if they have any yellow snot clogging them up?

[anutz]

the one i initially posted a pic of - the one i put red dots on - the crank case breather  :lol

[anutz]

good find - exactly as mine is layed out

[darrsi]

24 is news to me, that MUST be clogged up?

[anutz]

never looked into mine, i know its inline from the T piece that connects the pipes from the air box, i think its for allowing the air box to drain if it gets moisture in it...

[darrsi]

Mine must be full of yellow shit, meaning not breathing properly.
I need to change it then balance carbs again I reckon.

[anutz]

the crank case breather or the T piece and the inline filter thing it has?

[darrsi]

That number 24 jobbie.

[Jules-C]

Sorry for the confusion the airbox drain and engine breather pipes don't connect to each other.  I was working from memory when I cleaned mine about 5 years ago and checked them both so had it in my mind they connected directly.

The 24 thing has a piece of sponge in it and this will be solid with oil gunge.
