Cleaning air filter
What do you all use to clean and re-oil your stock air filter?
The SM says to use a solvant with a high flash-point.... I don't even know if I have anything laying around that would work. What are some examples? And as far as the oil is concerned... unless engine oil will work, I'll have to buy something else. |

I use gas to clean. Did it outside no chance of spark or open flame. The washed a couple times in soapy water. Rinsed in water and pressed it dry with my hands. No twisting that night tear it. Then coated with clean motor oil and pressed out the excess. On dirtbikes or if really dusty I always used foam filter oil which is stickier and traps dirt better.

I do the same as Greg, but I wash the filter in hot, soapy water after cleaning it with gas. I then let the filter air dry completely before oiling it.
To oil, I use filter oil specifically made for foam filters available at MC shops. Put the filter in a plastic bag, add some oil to the bag and massage gently to evenly distribute the oil throughout the filter. Take the filter out of the bag, squeeze out the excess oil, then reinstall. |

Very nice.... I think I will use some old lawn mower gas I have sitting in an can, and go with the motor oil technique, and pick up the MC-specific oil for next time.
Hmmm, I wonder if wife would get pissed if I raided her cooking supplies to pour gas in..... EDIT: I do have some Jet fuel, I mean kerosene, in my camping supplies. Will that work any better or worse than gas? |

not sure. the gas (solvent) cuts the old oil that the dirt is clinging to. the soapy water gets the remaining dirt off the filter.
feel free to raid the cooking supplies, just don't wash that filter in gas near the stove!! |

I clean with denatured alcohol in a baggie. That dissolves the old oil. Then I wring it out gently. I mix about a teaspoon of filter oil (sticky stuff) with about 2 tablespoons of denatured alcohol in a clean baggie and when it's dissolved good I drop in the filter, it doesn't have to be completely dry, and squeeze it until it soaks up the whole mixture. Then I let it dry for awhile. If you set it on a small fan pointing up it dries in few minutes but don't light a match! Now that the alcohol has evaporated it leaves a nice light, even coating of oil with very little waste.

I stopped by the auto parts store on my way to work today (unfortunately there aren't any MC stores close to me anymore). I picked up the K&M recharger kit; that is all they had. There is a spray to clean the filter (I assume it is useless compared to soaking in gas), and the oil is in liquid form (that is what I was after). I will assume it is all good on the OEM filter, unless I hear otherwise for some unforseen reason.

I believe the K&N stuff is for their filters and not as effective on foam. Not 100% sure but thats what i heard, from someone who knew someone, who had a friend who had a bike but doesn't anymore.

yep, the K&N filter oil is for the gauze type filter, not a foam type filter that the stock filter is. You need to get a foam type filter oil or just use regular motor oil as recommended in the service manual.
For a cleaning solution, you could use simple green full strength with warm water and it will clean the filter quite well. for a guy that doesn't want to spend money on your bike, you sure do buy a lot of the wrong stuff. |

Ahhhh... I didn't see that coming. OK - back to regular oil then.
Now, when is it safe to switch to synthetic? |

How do you properly dispose of the high flash-point solvent? I just ended up buying a new pre-oiled filter element for $10. *shrug*

Cleaning the filter myself for the first time and I can't seem to get the frame apart to clean the filter element. I'm afraid of breaking the plastic.

according to the service manual, the plastic pieces should just come apart. it does look like there are "pegs" that fit together in the center section. have you tried carefully trying to pull/unsnap the "pegs" apart?
