just how effective are they? i ask because i was thinking about the requirment to have them, to hold so much capacity, etc. looking back on a mission track day, where one bike had a mechanical problem and started spewing oil... even witht eh pan the oil ended up on the track thru turns 4567. remeber a similar incident from seattle. how effective are tehy when you are moving. isnt the airflow past the rad/etc just going to blow it out the back anyway?
