Power Valve Vent Tube??

Guys, just a quick question.

I noticed that the black vent tube coming out of the power valve cover (left side of barrel) on my bike was closed off at the end. I cut it open and some black goo dripped out for about 20 sec :eek:

Is this vent supposed to be normally open? I have left it open. Bike is new with 6 hrs on the clock. Maybe dealer forgot to cut it open??

Thanks for any response!

It is just a drain tube to allow PV spooge to drain off...leave it open.
They must close it off for shipping reasons.
 
Mine also arrived closed off, I have also left it open and still see some spooge dripping out from time to time, figured why have a breather and then close it off!

Mate, you live in a great part of the world! I am originally form PE in RSA. Did a tour through Swazi around 10 yrs ago - loved it. Must be heaven on your GG :D

I went to Woodridge college just outside PE for a couple of years, and if i had to (with a gun held to my head!) live in SA that would probably be my country of choice, but yes I love my GG in swaziland, unfortunately it is making the hills lower and flatter!
 
just read this interesting article on the ggpacific website and at the bottom they state that you should open and drain the PV via the vent tube after riding, maybe there is a reason to keep it closed and only open it to drain it?

I did not notice any differences when riding with it open or closed, and most bikes have them open
 
I'm still not sure how water got into my motor and toasted the right side crank bearing shortly after walking the bike across an almost seat deep fast moving river. (with engine off and cooled down) Wasn't thru the airbox, or carb area. I'm suspecting either the pv drain (open hose) or vent (routed up by the top of the rad).
I think I'm going to start closing the drain and keep an eye on it.
 
Mine was closed also on my 2010 but I was given a heads up by a member on this site. Maybe we should have a what to do check list sticky on setting up new bikes.
 
FYI~ Route that hose up to where the gas tank vent goes. Then get one of those short gas cap vent hoses for the tank.

?? Which hose ? The left side is a drain (can be plugged, just keeps the spooge inside til you drain it), and the right side is a vent. Its probable only purpose is to allow the drain to work and needs to be open to the air (at least when draining). A gas cap vent only lets air in, and water if its submerged, and keeps fluid (gas) from coming out.
 
What nhrider is saying is what I do as well, route the right side vent line to the nipple on the frame that the gas cap went to and use a shorty line on the gas cap. The right side PV vent is also the transmission vent (through the PV rod passage), and the frame nipple termination makes it almost impossible to get water in unless you totally sink the bike.
 
Another option is to route the RH hose into the airbox. Tuck it through the top right corner with the wiring loom, and seal with foam or silcone.
 
If not use an M6 grease fitting with the end/ball/spring drilled out. I do this with a 90 deg fitting as I have a custom damper tower 10mm more rearward that covers the hole making the straight fitting unusable.
 
The PV drain tube is only closed to meet worldwide environmental standards.

Clip it off next to the zip-ty at a 45 degree angle, similair to how you cut your carb. vent hoses, and let it breath / drain pointing straight down.
