Oil Traces In Airbox??
 

I'm just servicing the bike after our latest adventure and I've just checked to see how the air filter is as I have Pyndon's per-filter fitted. There's a fair bit of oil on the front intake. Should I be worried at all and any suggestions as to why it's done it??
A few pics below.

Thanks

You could try this:
Bypass the Crankcase Oll Breather Hose to AirBox with a Filter and Cap the AirBox Inlet.

Also, you may have a Bad Crankcase Seal:

Excess Blowby from crankcase breather, onto air filter

In my case I fixed the excess oil blowby from the crankcase by replacing "shaft seal ring 12x20x5B " part # 0760122050
avilable from munns racing online
it is located in the alternator cover and seals the Crankshaft Balancer .
if you do it you may want to order a new alternator cover gasket also

evidently the crankcase pressure is metered and vents through the crank balancer shaft .
If the seal is shot it blows major oil for some reason
mine was rock hard and shrunken . It was blowing oil everywhere , especially when doing over 90 mph sustained

I've got a pre filter fitted and looking at the air filter it's done a crackin' job as it looks new apart from the oil trace. Can't log onto the link for some reason :scratch

My money is on prolonged high speed running - ie 200 miles @ 90mph?

Clean it up & look again in a couple of weeks.

My 950 did the same. Found mine was due to a balancer shaft seal failure. The case breather port is right above this seal. Its very easy to check and replace. Just make sure you have a spare ignition cover gasket.

This, it's easy to change. Gasket is $25, and the seal is $10 or something.

I just ordered the parts for my fix. I'll try and take some photos when I get in there.
May install the K&N breather filter if I can get hold of one.
There was an K&N part number floating around somewhere. . .

k&n 62-1110 this one i used
