Oil in breather tube?

[tconroy]

Is it normal to have oil go in the breather tube and down into the airbox chamber and out the chamber drain? I have never cleaned this tube out and its been 6000 miles before this showed up.I am due for a valve adjustment which I will do next week.Any answers would be helpful.

it's related to an overpressurization of your crank case..

could be rings or valves...

Actually, it's probably perfectly normal.

If you're talking about a quart of oil, then yes, you have a problem. But over a few thousand miles, a couple of teaspoons of oil and general engine funk is going to make it through the breather tube and into the airbox and generally make things kinda nasty and dirty in there. A little bit inevitably escapes, so things are generally a little oily and funky around the airbox on even the best-kept GS.

There should be a drain tube attached to the airbox, so it's worth checking that it's routed and attached properly.

Can The Hole Where The Drain Goes On The Bottom Of The Air Box Be Plugged Or Should I Run The Drain Tube???? Thanks

I would run the drain tube to keep all the funk off the air filter.

20K for mi on my bike, and my tube and airbox is always dry. Excessive oil is somehow being blown past the screened breather element in your valve cover. Could very well mean you have excessive piston ring blow by. Do a compression check. You should be around 140-150 psi

I Ordered A New Drain Tube From Suzuki To Install On The Bottom Of The Air Box And The End Has A Plug.should I Leave This Plug In The Hose?? Is There Supposed To Be A Rubber Groumet To Hold The Hose In The Air Box ? Thanks

Im talking a couple of drops on the garage floor.Im going to do a valve clearance adjustment as soon as my feeler gauage I ordered gets here.After I hit 8 g's it's clattering a little more than usual.At first start I have to idle past 2 g's till warm up( 2 minutes) than the clatter is a lot less noisy.Would valves out out adjustment also cause this?I do keep my oil close to full line also.

It wouldn't be a drain with a plug;-)

A little discharge is normal/acceptable.
