Air Filters: To oil or not to oil...that is the question!

24 posts in this topic

Ok. Here's the deal.

A local MX pro and mechanic recently told me that he doesn't oil his air filter unless he is riding a dusty track. He said he just uses one or two filters per day at his regular hardpack track and washes them with dish soap at home. Easy.

I think he's crazy but...but he is a motorcycle mechanic and is currently ranked #2 in the region. Who am I to judge...but what do you think?

Can you run a bike in ideal conditions without oiling the air filter? And why would you?

Riding motocross with a dry filter isn't the smartest thing to do.

air is never 100% clean, even if you dont se it, dust is always there. I bought a second hand bike once and had a dry air filter on. The air boot was full of dust inside......Even if you use specific air filter oil, if it dries a bit, like in a few weeks, dust will go through

Hmm...perhaps my mechanic is hoping I'll follow his advice and run an oil-free filter. Crappy way to drum up business, no?

Yes you can do it, but you'd better have deep pockets to rebuild your engine on a regular basis.

Why would someone do that, well I guess he's thinking the oil in the filter is restrictive and is hoping for better throttle response.

You should tell him that the oil in the crankcase/trans. is restrictive as well, and he'd get better performance if he ran without engine oil.

Hmmm.....

Agreed, not putting oil on your air filter is asking for trouble. Some people give strange advice though, it's always good to check.

My advice would be to borrow someone else's bike and try it. Run for a couple hours, then take off the filter and examine the carb and intake tract.

I forgot to oil my filter once (yah, totall noob) on a dualsport ride in the sierras. The inside of my airboot was quite dirty and so was the carburetor. No bueno.

I can't imagine not oiling my filter. Especially on a 4 stroke, which pulls a lot more air through.

It totally amazies me what people say. Just use common sence. If it sounds stupid it is stupid. At least your smarter than the mechanic and at questioned what he said. ALWAYS USE OIL.

why not just oil your normal filter, then get filter skins, oil them and throw one on. once its dirty, replace the skin with another. once you go through all 3, wash the skins and the filter....

thats what i do. the normal filter will look freshly oiled no matter how dirty the skin gets usually

I have heard that some people only oil the outside of the filter and not both sides, I always do both!

a properly oiled filter will be oiled on both sides, now you dont have to physically oil the inside, but if you have a good even oil distribution, the inside will be oiled

Thanks for the positive reinforcement. I know from my 2-stroke days that a good clean air filter was the way to go and naturally assumed the same for 4-strokes (this is my first thumper). But I had some doubts after a pro said not to bother with the oil. He said that oiling was an old-school way of thinking and not required on today's modern 4-strokes.

Staying old school and oiling the filter!

Maybe he was just pulling your chain and being sarcastic. Either that or the education system in Brazil is severly lacking.
