crankcase breather and airbox drain

[dropman]

Today was the big day because it was first time I took off tank on my TA650 and checked air filter.
I am confused about all these hoses running down to base of center stand...

I found one big hose coming right from airbox. That hose has no plug at end and comes DIRECTLY from filtered side of airbox. It seems strange to me, because its possible to get dirt through that hose.

There are also few more smaller hoses near. One of them should be crankcase breather hose (it should be with plug, but my bike has no such plug there).

1. Is it normal that bike can take unfiltered air directly through drain hose?
2. Should i plug the drainhose?
3. Should I plug crankcase breather and how can I find which hose is crankcase breather.
4. What else should I know about that hoses?

p.s. About 10cm of drainhose was burned because it was sitting on that square exhaust box (didnt know how to call it). So maybe there WAS plug at the end of drainhose?

one of the hoses is overflow from fuel tank
fill too full on hot day and it will expand ond drip out
make sure that they are not directed to exhaust pipe.
others will be some sort of drain/breather
I would check that they do not get choked with gunge etc from below
other than that I would do not much else.

The engine breather goes into the airbox, halfway along on the RHS. The airbox drains from the rear left corner & is the big pipe that you mention - and YES is should have a bung in it.

The other pipes are just tank vent/ overflow pipes etc.
