690 Enduro - oil in the airbox

[dmoo1790]

I have a tendency to rest my bike on it's side at times. ;) I believe this sometimes causes oil to drain back into the airbox somehow. I have twice found a fair bit (maybe 50~100 ml) of oil in my airbox. Anybody else had this happen?

Yes definitely my bike must have the same imbalance system as yours ... I always thought Suzukis and KTM were wired differently :wacko:

They are. My DRZ never puked oil anywhere when it lay down. Orange bikes must have weaker stomachs...

Oil in the air box? Don't you think it might be from the air filter? I think oil would struggle to get through the carb.

Um Bart...where is your engine breather routed to?

50 to 100 ml of oil in the air box is a lot of oil, it must run like a drunken sailor when it goes back through the carb :wacko:

The carb? You got a carb? :) Nope, no smoke. The shape of the airbox means most of it pools at the front unless I do a monster wheelie... not. I only know there's some spillage when I check the oil level. Had to top up the oil twice so far in 6000 km but at least I'm pretty sure it's puking, not burning, oil. Pretty sure it's coming from the breather pipe which plugs into the airbox near the front.

Well the strange chaps at KTM decided to put a paper!? :shit: air filter in the 690 so there's probably no oil in that. Or at least there wasn't until I involuntarily oiled mine. And we don't do old fashioned carbs in the 690 world. We have flash, gee whiz fuel injection. :)

The carb? You got a carb? :) old habits die hard....I mean "trottle valve body" ;)

As Nutso says it will be off the engine breather. Going too hard my lil friend

[NordieBoy]

I just found my TT gearbox breather is T'd to the airbox and behind the right footpeg. Where it splatters over the right hand side of the tyre. Been wondering how it was getting splattered when the chain is on the other side...

Carb...injection...it's all the same really. Turns fuel and air into something that goes BANG. :yawn:

And I thought the oil in the bottom of my air box was from the over oiled crappy K&N filter....oh well. :wacko:

Yep - the crankcase breathes into the air box small amount of oil normal - 100mls a bit much.

[dmoo1790]

The breather system on the 690 is not as simple as I thought. The route oil would have to take to get into the air box is pretty circuitous. So I'm not sure simply lying the bike down should allow significant amounts of oil into the box. Something I'll need to monitor and fix if it still spits oil even if not dropped.

Only time mine has ever had oil in the airbox is when the bike has been overfilled with oil.

Make sure you are checking your oil levels with the bike completely flat and the engine is warm.

Funny you should say that. I _may_ have been guilty of topping up when the oil was cold but that was only _after_ finding oil in the airbox. Had my bike serviced on Monday and checked the oil level today when getting fuel (so oil warm) and the level looks pretty damn high. Right to the top of the sight glass. Maybe I'm foolishly thinking the professionals know what they're doing.

At the price of that Swiss syrup I would've thought the contrary would be the case - level to low. :laugh:

Sounds like you're onto it there. The pre 690 LC4 motors are very prone to spewing oil into the airbox if overfilled, my 640 Adventure did it once after a particularly energetic raping one day on the highway, enough to drip out the airbox drain over the shock mudguard and onto the rear wheel. Eeeeeek! Thereafter I kept a close eye on the oil level and never did it again. Never had an issue after it had been on it's side. Measure that oil exactly when filling 'er up :yes:

And if the price of Motorex is crippling ya, try some of this AGIP synthetic goop http://www.trademe.co.nz/motors/car-parts-accessories/oil-additives/auction-461324600.htm

Yep, me as well.....The 640A had to be bloody exact with the quantities...I recall stopping and seeing the exact same thing, air box was full of oil. the rear tyre splattered and the swing arm a mess. I thought the engine had shit itself, but it was my fault, just putting a tad too much into the engine...:no: It was a matter of draining a little and then re-reading the manual :facepalm:
