What happens is the oil that normally blows out in a gradual mist collects in the back of the "bullet" of the SA, and then drips out. The packing and the outside of the bullet is usually fine. A regular silencer with the same jetting would run perfectly clean with no spooge drip. I think this is common with a Krizman type SA. This same thing happens with the TC2 on my '07 250, but to a much lesser extent, probably because its a lot shorter than the KTM silencer/SA.
