Air filters, Oils arent Oils Sol

[GregMember]

I have been seeing way to many dusted bikes of late. Fact closed intake valves are a result of dust entry.
Last year while setting a float level in an XR650 (not mine either) the air box was found to have oil all through the bottom of it and only the bottom half inch of the filter had oil left in it. That means 95% of the filter had no oil in it meaning no protection. When checked the engine was lacking compression, when the tapper covers were removed and engine set up the intake valves had less then .001 clearance. Luckily the XR runs screw and nut adjusters and a quick adjustment saw the compression back and the bike starting easier

The owner was using a filter oil that was claimed to be good because it was easy to clean the oil out of the foam, which would be the case as the oil wasn’t in the filter after we worked out about a week after it was done.

I use Motul filter oil, pay the same price as any member can here. It’s no harder to clean then anything else but remains in the filter and that means it’s there to catch the dust which is the reason you use oil. There are about 3 filter oils worth using IMO and one because it’s easy to clean isn’t one of them

The videos show that a filter that has been in my bike for over 11 weeks still has the oil up the top of the filter

The filter cleaning video isn’t complete, I didn’t show washing it in warm soap water and then rinsing in twice in water. Once dry I oil it in a bag or by putting it over the top of the open bottle and tipping it over putting dots all over the filter and when done squeezing the oil around the whole filter until its through the filter evenly then making sure any excess is wrung out.

Use a tacky oil that stays in your filters please guys and gals it pays of in the long run

Another little trick we have found to work a treat is to put your Filter Oil in a squeeze bottle (IE Tomato Sauce Bottle). Then you can squirt as much or as little oil onto your filter as needed.

Alot cleaner then any other method I have used and you waste next to no oil either.

Great idea bowie. I always pour way to much oil on the filter then have to squeeze the excess into a clean container then pour it back into the bottle.

Good thread TB.

I have always uesd Motul filter oil and I have also being using filter skins for the last couple of years.

heres a good example of why one should oil their filter correctly.
there was a small colony of rodents living in the air box this was in. good job some mates decided to check it for the owner!!!!!! :ohmy: :ohmy: :ohmy: :ohmy: :ohmy:

And the same filter just before it goes back in after it got a good coating of castrol spray on air filter oil, my preferred product, it works fine for me.. !!!

I had the spray oil used once by a bike shop and ALL of the oil was gone and coating my air intake and butterfly. NEVER AGAIN will I let someone else oil my filter or use spray oil.

First point I don’t care what you use just be aware is all

Second point that stuff is crap it’s easy sure but it doesn’t get through the filter and runs out mate.
We had our air cleaners done on the 3 states trip at Canberra as you may know. Ask Moose, Boulder or Nickj about how good spray oil is mate? Those air cleaners were in less than 6 days :ohmy: guess what yes spray oil used Nick knows the brand I think.
Ask Gaz we found his filter oil lubing his chain :laugh: Wasn’t over oiled just running down through the filter and out the air box drain not Gaz’s fault just the oil wouldn’t stay in the filter

I will do an air filter test using three different oils, I will oil three filters and hang them up and will video the filters after two days and a week to see what happens :huh:

Thats just a disgrace Boony :ohmy:
Who in their right mind would let an air filter get sooooooo dirty :whistle:

Did the rodents bite you ?
I have been training them like attack dogs

Bol :woohoo:

[Bruce CurtisMember]

I totally agree with TB with this, one caveat though, I also find in a bind chainsaw bar lube is really good too, it is tacky and catches the finer particles well.

Having said this I have never ever in 40+ years dusted a bike even when using plain 2t oil as a filter oil, but then again the filter media has changed a bit since we did that.

No excuse for dusting an engine unless the filter disintegrates.

[DeanMember]

In a Pinch when Piss Poor Planning prevented me from using my usual trusted oil of choice I have used Chain lube :laugh:

worked a treat

So bols does heidi get lubed up properly before you ride or is she just as dirty as the WR’s box. Good to see your maintenance schedule is still as tight as ever.

i dont think there is anything wrong with that easy cleaning, no toiling type of filter oil.

in fact i’d go as far as saying its user error that causes this problem.

if the instructions are read properly for this product, it will be noticed that the filters are to be left out to dry before being reinstalled. the spirit based emulsion needs to eveporate to leave the active ingrediants stuck to the filter. if the filter is not dry before installation (when it is dry, it losses its chalky look) the imulsion, including the all important oil will drain out.

i leave mine out to dry overnight, on some newspaper, seal side down.
i thought everybody did this??

looks like a poor tradesman blaming his tools to me :laugh: :laugh: :laugh:

Sam and I use a hairdryer on low heat high fan to dry off our filters.

Speeds up the drying time but still leaves enough time for doing our makeup

You could be right Menace, I am only offering an opinon from trying different brands etc speaking to people at the dusty meetings where you ride 750kms in the pack sucking dust :pinch: To check yours and others theories mine included I will do 3 separate filters with No Toil, Castrol spray and Bel Ray or Motul I will video each one being done and follow the instructions to the letter. After two weeks we will be able to check on video if they still have the oil in the filters. I have seen the results which is why I wrote this but will do the experiment under controled conditions to confirm for myself as well. If I am wrong I am wrong won’t be the first time :laugh:

Even last night I picked up a bike that I am fixing for a guy that’s been dusted and closed the inlet valves (DR400) I will do a step by step on the repair to show the effects of dust entry and how to remove and reinstall the head and get it running 4 stroke style :laugh:

Like I said before I don’t care who uses what I only wrote this because I keep seeing dusted bikes more often than not from people taking short cuts and cheaper options. There have been some great tips here on the thread including the news paper, the tomato sauce bottle, filter skins, the hair dryer etc BTW the clothes dryer works great when the minister isn’t around :laugh:

The two stroke guys are laughing it isn’t as critical on a two strokes nor on an old XR but the modern four stroke it is
