« on: December 19, 2012, 07:27:25 pm »
The two breathers coming form the top of the head, the rear one runs to the black box thing between the frame and the carb.

now where the heck does the other breather run to?!

The smaller tube that is in the front of the head  ???

It goes to the frame close to the oil filler hole.

My guess for the one from the top of the engine is that it connects to the airbox.  This is a common arrangement to allow combustion by-products etc to be recycled through the combustion process, while filtering any air that get sucked into the engine. Sometimes this pipe is routed via arrangements to prevent the intake from sucking the oil out of the engine.  In the old days this pipe was simply routed towards the ground allowing ingress of road dirt. 

It is the pipe from the top of the oil reservoir which stumped me.  It's too short to reach very far.  I wanted to get a look at another DRZ but I didn't get a chance.  Go have a look at Milddog's DRZ or swing by Suzuki South to see if the have one on the floor.

did some digging through the parts diagrams and it is an oil reserve tank overflow (top of the reservoir) that long one is for the radiator

Will double check on another DRZ today too.
