I've never seen one live and in person, but I believe the filter is that black flat top surface you see in the link. I think the OP indicated that the top portion was not sealed up tightly against the bottom part.

 

If this is the case, perhaps the sand got in because the filter on top of the box wasn't sealed down properly, and repairing this will solve the matter for the future. But IF the arc filter is on top of the box, and therefore does its "filtering" BEFORE the air enters the box, I would think that sand in THIS box would be a possible problem for the engine, because there is no filter between the interior of the box and the throttle body. My modified stock air box does not pose a problem if trash gets in the air box (which it does), because the air has to pass through the filter before entering the throttle body, and the trash is blocked by the filter. But if the intake design is such that sand and other trash that gets into the air box has already passed by the filter BEFORE entering the airbox, that would be a problem I would want to fix pronto.

Thanks,
Richard

 

no there's no sand mounds under the exhaust..
no sand flowing out of the pipes also...

Did sand get beyond the air filter? I thought we had finally settled on the notion that it had not.

yes it did

 

Ouch. Sorry to hear and did not mean to cause confusion via my misunderstanding.

If that's the case, bend over, because it's coming!
