Sprint Rogue pipe where does it go!?

hi I think that is to the expansion tank behind the rear side panel. will check tomorrow.

 

Could it be a crankcase breather? Should go to the airbox if it is.

 

Agreed, the size and shape to me says crank case breather pipe that locates to the bottom of the air box.
Especially as there is trace of oil in it. May be worth totally removing it and cleaning it through first before refitting ifthe oil/gunge is excessive.

Having said that, it locates to the side of the engine, are you sure this isn't a coolant pipe as it almost looks like it goes to the cooland pump :/
Check everything, radiator pipes are all correct.
Have you been working on the bike, if so what did you do, does it run okay,

 

had a look, it goes under tank I think these guys are on the right track
you need to remove tank, I think, of so be careful of the fuel hose connector and replace the o-rings on rebuild.do not leave tank off, as if it has fuel in it it will expand.

 

Okay, good good
Then as suggested, lift the tank and take a look for aroundthe bottom ofthe air box for a hole it would fit on.
The fuel line for the tank (if like my 2010 Speedie) unclip and seal itself so no leakage..maybe just a little drip so have a cloth handy...and dont do this with the engine or exhausts hot
uses some pliers to secure the hose clip in place

When I collected my bike, it had all the pipes to the airbox and tank disconnected!
Case breather, tank overflow and tank breather pipes

 

On my Speedie, there are two black pipes from the tank, both are not connected to anything as they are there for venting and lead to the bottom of the bike in front of the rear wheel.
One is an air pipe to replace the fuel as it is used so there is no vacume in the tank and has a one way valve about two inches from the tank connection, the other is a fuel overflow pipe for draining excess fuel when you fill it, this does not have a valve.
I hope this helps
