They went back to stock filters.
Let me understand this ('cause I run dual K&N filter pods on my '82 R100)...Are you directly attributing an increase in silicates to the K&N?
Any other variables you might consider besides the K&N, such as riding in dusty environments, dirt riding, longer change frequency??? Anything else?
I'm curious because although I may concede the square OEM filter may seal better than the K&N and that's just a guess, I really cannot imagine a filter POD, appropriately treated with the oil impregnating sequence could deliver any measurable increase in silicates even on just ONE change! I cannot imagine ANY increase using the pods...it really does not compute
Before anyone should be willing to diss a product like the K&N's (at least the pods) I'd say lets here more experiences...I really can't buy that story at this point!
