possible oil leak...

In my airbox between the two plenums the little breather looking thing seems to be leaking oil. And according to TAB they think it may be the cause of my bad idle problem. Ive went through all the steps to diagnose if it was their tuner or not and it doesnt seem to be.

Anyone else have any ideas or experience with this?

The bike barely has 150miles on it. 130 of that has been with the tuner and slipons it just started idleing badly recently.

Could the new hi-flow air filter have been excessively oiled causing this?

Not sure if we are talking about the same thing, but there is a connection between breather and airbox, and if the airbox is mis-seated the connection leaks. Remove airbox (easy job) and replace making sure everything lines up. This is a common error made when the bike is serviced. It won't be your idle problem.

To check your idle, remove TAB tuner. It is not required at idle.

The most common cause of idle problems is a faulty or dirty IAC. That seems unlikely on a new bike.

Unlikely.

Oil accumulating within the filter housing is usually from the case breather condenser (the small cylindrical plastic "can" that the breather hoses connect to). Excess breather condenser oil (normal quantities drain back into the cam covers) results from either too much oil in the crank case (check the dipstick) or too much "blow by" (rings are either worn or not seated).

If I remember correctly, another member here had that same problem. He corrected it by placing a single wrap of electrical tape around that center canister/breather where the top clips onto it. The top was loosely fitted (mine wiggles too - but doesn't cause the oil problem) and the tape snugged it up and solved his problem. It's an easy thing to try. Good Luck!

I have removed the auto tuner and it still idles rough.

This just started recently, so possibly bad gas, fouled sparkplug, loose ground (there are 3 - check them), maybe spray throttle body cleaner in the IAC while it's running (I'm with Louis on this due to the low miles, but sh!t happens). Good Luck!

May be bad gas I did buy from a lil hole in the wall because I didn't plan well.....

If not the dealer said a little fluctuation in the idle is nothing but 500rpm or more probably is an issue, and its not that big of a gap, I may be over exaggerating it...

If these bikes are running right the idle shouldn't fluctuate over 100 rpm high-to-low. Don't believe the dealer, they've got a conflict of interest most of the time .

Two plenums?Do you mean the iac port between the two throttle inlets?if that port is full of oil then that will be the idle problem.clean the iac port with compressed air or something like carb cleaner or top end cleaner.there may be an obstruction in the port allowing a build up of oil in the port.if i have this wrong ,please ignore.

He said the oil was "in" the airbox. The IAC port is below the airbox. But then again, maybe I have it wrong -

The oil is in the air box.

Put about 120 miles on it today in the cold trying to run this tank out so I can put in fresh gas and see if that helps.

Oil leak fix

I had an minor oil leak that was pooling in a pocket on the right side by the water pump / stator area. I had the stealer fix it Saturday 10-27-12 when I brought the bike in for the 5k service. They replaced both the breather O-ring PN 11391K ($.95) and the throttle body gasket PN 29439-01 ($2.50). It's only been a day since they fixed it but no more leaking and I rode 150-cold Chicago miles. You may have the same issue.

Did it idle a little rougher than normal?

post up some pictures of the oil in the airbox please.

what is the oil level at in the crankcase(on the dipstick).

what work has your dealership done to it.

is your throttle body gasket ripped.

these motors are known to have the map sensor go bad but what do i know. excessive oil in the airbox usually means the oil was over filled by someone. you idling issue could be that the throttle cables are not adjusted properly. the front and rear breather tubes are notorious for leaking on these bikes too.(piss poor design)
