Cleaned my air filter today, it did it's job properly, there was no dirt at all near the horns, under the filter. Problem is, that there was dirt inside the Dial-a-jet hose where in meets the DAJ. I checked, and my foam plugs are still in place. Has anyone else had this happen?

 

Yep,
Don't worry the filter is dry that is why. Don't oil the filter it will stop the air flow which the DJ needs to work. I usually just blow them out twice a year, from the DJ to the filter end.

 

The dirt won't clog the DAJ air holes, in the body?
