Just ordered a new malossi air filter for the GTS300.

My question is do I oil it or put it in dry?

thanks

I would follow the instructions that come with it. An oiled foam filter should be more effective than a dry one.

Thanks for that.
I thought I had read about someone putting one in dry.

I always give my malossi a light spraying of filter oil then rub it in a bit. The only times I have heard of people using them dry is on track days or on bikes only used on tracks.

Oil it of course! I've used just the same oil I put in the engine (Shell Rotella T6) and have had no problems. I'm not sure you need the super sticky expensive stuff.

Do you soak it and squeeze it or apply to the outer surface?

Thanks

Yeah there is always a debate on whether to use engine oil or filter oil. I have no idea if there is enough of a difference to really argue for one over the other. I use the spray filter oil because it is faster and easier to apply for me.

Thanks Chaps

I use Putoline fully synthetic 4T oil so will use that.

The best way to oil it is to mix the oil with some gas and mix it up well. Then soak the filter element in the mixture, wring it out and let it dry. The gasoline will evaporate but the oil will be embedded in the filter foam.

As a precaution, place the filter on some paper towels (over some newsprint) and then compress to expell excess. Don't place directly on newsprinte...ink will transfer to foam surface. You can then place filter on some shrubs air have it air dry (evaporate). The residual oil in the filter acts like a "fly paper" / stick 'em to pic up particulate matter. Subsequently, as need you clean it out and reapply oil / gas mix.

Here is the way I do it to avoid a mess - Pour some air filter oil (Not alot, you can always add more) in a large zip lock bag , then put the filter in, zip up the bag after getting all the air out and work the oil into the filter.

The filter should be completely lightly saturated. Then take it out and using rubber gloves gently squeeze all of the extra oil out of the filter. Let it sit for 1/2 hour in a well ventilated space to release the alcohol/ gas fumes, then install. You would not want a backfire with the fumes. Gets ugly real quickly.

With foam filters I like to have 2. I have a clean oiled one ready to go when the time comes to change it. Then I can clean the dirty one at my convenience store it in a zip lock type bag ready for service.

Oil is necessary to make the foam stop the dirt.

I think the OP is asking because the instructions on the Malossi say to oil if you will be on dusty dirt roads and not to oil if riding on sealed roads.

As all my riding is on sealed roads, I did not oil my Malossi air filter.

Cheers,

Chris

thanks all for the tips.

Yes all my riding is on sealed tarmac roads town/motorway even side roads. Not many dirt road in South Yorkshire.

Having said that I don't think oiling the filter anyway will do any harm.

I was confused by this too. Though I do remember malossi recommending it if you ride on dusty dirt roads I don't remember the instructions saying not to if you ride only on sealed roads. I may be mistaken though. Will have to check my spare when I get home.

I use the specialized spray oil. No one cleans their air filter as much as I do. I am really anal about that. I do it with oil changes. I use a plastic grocery bag, put the clean filter in it (I also have two), spray all around and on top, flip it over wearing gloves, and then do the same to the other side. So I guess in response to your question, I think I am between soaking and applying to the outer surface.

Whether one uses filter spray or filter oil, they are both very sticky and in no way compare with engine oil. When you consider the function of an air filter, which is to trap airborne particles, not to lubricate anything, you might think twice about using a liquid that was formulated to lubricate, not to trap airborne particles.

Just saying.

If my GTS sported landing gear I might be more inclined to use my can of filter oil more often. Either method will be just fine.

Thanks a lot for for all the advice.

Did the filter change yesterday, put the filter in a bag with a mix of oil and fuel
then worked the mixture into the filter. then got rid of the excess with some paper towels and let it air dry for a while.

Just scored a quart of the recommended Selenia air filter oil and will use it next filter service, but I have have been using K&N spray oil and it's been working fine, spark plug shows no signs of lien running.

Those were the days. It seems like only yesterday. Hang on it was only yesterday and it went in oiled.

I'm quote surprised just how long it took to get a reply like that

air filter
Good afternoon everyone'

I want to thank you for this post. I got curious about MY air filter. Eight or so month ago, the shop informed me that my filter was soaked in too much oil. They told me that they repaired the problem. I cracked the filter housing (thanks wiki) to take a look: it was bone dry.
