do oyu think i am running any ris if i am on a track with no mud and very minimal dust?

 

no, however I would not make a habit of it in dusty conditions without a filterskin- they really are a great product.
As for blaster intake boxes, you can remove the lid and really not worry about anything. I removed mine a looong time ago and my air filter doesn't ever get mud or water in it.

 

Shoud be fine. Run a filter skin. and wash your bike and cleaner after every race or full day of riding.
