Chewing the fat about foam air filter maintenance

Haha. It used to be that you should only use leaded to clean your chain as lead is a known lubricant. It was introduced into petrol as both a lubricant and knock suppressor.

However, many believe that 98 will do the same whereas it has little or no lubricating properties. The same applies to 95 and 91 octanes although 91 is still the preferred octane for air filter cleaning and it can be bought relatively cheap with a shopping docket

Probably just clothes detergent anyway, I have had a good run with no toil, not so messy.
not sure who thought up the name for their air cleaner grease though -

Very popular around Sydney's Mardi Gras scene............Russ would know for sure

So

So what would you prefer to talk about davo...?


... the correct oil mix ratio for a pre-mix converted X7 perhaps...

Easily good enough I have to agree..unless you have visions of your filter lasting the life of the bike

Kerosene, rinse off with fresh water from inside out, soak and squeeze in warm soapy water, rinse out with fresh water again. Hang up to dry. Massage Motul filter oil though and squeeze out excess. Apply grease to sealing surface. re-install and let set overnight.

kezza got all that down into two lines...

Only two lines but it makes filter maintenance into a hobby

Any one ever done the wash cycle in the washing machine with the air filters.....? No Toil claims it's friendly? High doubts on this for me . I'd be paying for a new washer for the little lady. Tried and true gas ..hot soapy water ....clean water squeeze out gently ..air dry and if it's air early morning oops forgot? I'll strap it to a fan for a hi speed dry.oil generously into a plastic bag and smoosh around until it's even coat add more if necessary repeat....same as below posted. ...moose oil seems too snotty. Bel rays works just fine ....Grease the seal....river crossings will bite.

I wash foam filters in Dawn dishwashing detergent, dry 'em in the sun, apply 30W oil, wring out the excess, install and go. It's the oil that does the work, the foam is merely a media to hold the droplets of oil which capture dust.

Which is why it pays to use filter oil which sticks to the foam, rather than motor or gearbox oil which will eventually make its way to the bottom of the air box under the force of gravity.

In my experience the gear oil works best on stock filters as the aftermarket ones have a corser foam which causes the the gear oil to run down to the bottom and not stay at the top

Yep. I love my filter maintenance alright and my bike loves me for it...

wait till your missus catches you with parts in the dishwasher

Put on a pair of nitrile treatment gloves (and clear safety glasses) pour a small amount of belray onto the outside of the filter then gently work the oil into the foam with the finger tips watching the inside of the filter to ensure it comes up consistently blue and work your way round. Once finished throw the gloves away.
Never had oil from the filter in my housing yet - just don't mention the PO overfilling the latest bike in the shed and me picking it up riding home 700k :eek1
Filter foam was dripping by the time I got 100k up the road.

Sounds like a translation from a Chinese service manual.



As for the air filters disintegrating, They all do that. What you wash them in will depend on how quick. Even the oils will break them down.

seen a couple a few hurried MX mech's do this (by misstake) in a rush between heats... :huh

... not to mention the odd hopps addled mech late of a friday night in the shed...

What? Rage in the intake, or rags in the intake?

When riding old WR450 always used Motul filter oil in air filter and sock filter and a spare in bumb bag when dusty end of day a quick change or take out sock and clean filter ready to go
