No..well... not very much anyway. At least on my Z8 I have tried with a gas blower on the intake while having my shop vac on the discharge end...running and not running.. before opening and found that I may have got the loose stuff out but all the stuff packed in the primary and the back side of the secondary along with stuff laying on the bottom was still there. This is why I went to a full filter system on the intake.
But...I did not try putting a vacuum on the intake behind the seat so..give it a try and see. Can't hurt.
