Here is the order.....Screw, Spring, Washer, O-ring.
Put all of the parts on the screw and then put the screw in the hole.
If it isn't done like that, the O-ring tends to get pinched and damaged. If you don't use the washer, the spring tears the O-ring. If you don't use the spring, the screw backs out on it's own.
Once the O-ring is damaged, the fuel leaks out and also gives a variable rate fuel/air to the idle. But is dependent of engine temp, as to when this changes the ratio.
(Man........ where's Cody? he could use this info........)
Don't burn it, because even if the K&N sucks it'll still filter better than nothing at all.
By oiling the twin foam and wrapping the dry/un-oiled K&N, you are improving the Filtration, at least by theory.....
But if there is a gap in the fitment, the piss poor K&N will still filter in that one area. But, realistically, the majority of the filtration happens everywhere else.
IF the fitment gaps are really that much of a concern, just put a few drops of oil on them, and you are still not "Over Oiled" because the Twin Foam is carrying the oil and dirt.
I know that I am opening the doorway for Arguments....... but remember it's just an Idea/theory and is untested......
