Air Filter Surprise

Post by okie2ee »



I have seen the other photos of stuff found in the air filter compartment. Figured I better change my filter with 53,000+ miles on the bike. Look what I found:




Replacing my filter with a K&N filter, hope I can feel some improvement, fuel consumption is pretty bad at present, also plan on changing out plugs.

uh, there will be no improvement with a K&N filter.

the only change will be more dirt, a lot more dirt in the engine.

the K&N filters have failed every single filtration test that has been published.
I would not touch one with a ten foot pole.

my bike had one when I bought it, threw it in the trash.
the OEM filter is good for 50,000 miles or more with no loss of power, what more can you want?

it is too damn hard to get to those filters anyway, why put in something that require continuous maintenance?

K&N is last

53,000 miles is as good a time as any to change but you did not say how many years and months passed between filter changes.
Where the bike is parked, not how many miles are on the bike, would be more important to me how frequently I check the filter.

The OEM filter is more than sufficient for the filtering needs of your engine.

DaveO430 made a grill just like you showed and put it in the intakes of my 1800.

worth every second it took him to cut it to size, and cram into the intake port.
