Can I "Pump Spray" My NoToil Filter Oil?
(Click here to view the original thread with full colors/images)

I was thinking about this the other day and I just wanted some opinions: I don't see any reason why I couldn't pour my NoToil filter oil into one of those generic plastic bottles with the trigger pump sprayer on them, do you? My thought was that instead of pouring it out of the bottle and working it around the filter that I could spray a much more uniform layer of oil across the filter and then work it in from there. Keep in mind that over-oiling the filter on the 426 is a bad, bad thing to do!
Whataya think?

The only thing I can think of off the top of my head is that it might "gum up" the sprayer nozzle when it dries...hummm? give it a try and let us know!

I've put mine in a pressurized sprayer. Get them at Harbor Freight or Grainger's. You fill the bottle and then pressurize them to 100psi. It only will flow in a stream nozzle, the fog nozzle just locks up with that heavy an oil. No-Toil said that they use isopropyl alcohol as a carrier and I thought about thinning it out some, but the stream works pretty well.

I've noticed the oil tends to separate fairly quickly, carrier at top, oil at bottom, my only concern would be mixing, guess a good pre shake then the first few sprays on a rag/paper will solve that.

Yeah, there is a note on the bottle to "Shake well". I think I'll give it a go and see what I think. I'll report back the next time I have a filter to oil. Might be tomorrow, might be next month, all depends on the weather lately.

I've already tried the trigger spray bottle method. Unfortunately, the oil seems too thick to generate a spray (or pressure is not great enough) so it's basically a stream that comes out. This was still better that pouring, I thought. Then a week later when I went to use the spray bottle again, the valve was plugged solid!
I am now going to the flip up spout like those found on many shampoo bottles. The hole is big enough that I dont think it will plug up, and it's still better than stock opening.

NoToil sells the filter oil in an aerosol can that can be sprayed on the filter. I use this method exclusively. It works. Probably, they thin the oil with more alcohol to make it work with the nozzle on the can.

Out here in the west (especially lately) all of our races are very dusty and getting the filter completely oiled is crucial! It is easy to mis judge the coverage so I use a measured amount of oil. I put 4oz oil on the filter in a zip lock bag and message it in. I have a bunch of filters so they will sit in the sealed bag for a month or so and then I re message the filter and put it on the day before a ride so the alcohol evaporates.
I used to just put on the least amount needed to get coverage, then after a dusty harescramble I had mud built up in my carb! There was a spot the size of a quarter that wasnt covered good enough. I had to rebuild the whole motor, botom to top!
This last weekend we had one of the dustiest enduros ever and I know of 3 people personally who had motor failures due to the dust, I rode the whole event without changing mine and no dirt (taulk powder auctually) got past.
I saw the aresol can for no toil but I like to supersaturate the filter and let it dry off a bit before I use it. I dont know how suspetable the 4 strokes are to a too oily filter but I dont think they would like dirt eithor. Just my own experience.

I race Hare Scrambles and enduros in No. Calif., which can be quite dusty, or muddy and wet depending on the time of year. The aerosol version of NoToil has worked well for me. I have had no, repeat no, upper or lower end engine problems in two years of racing. I race almost every weekend between the months of October and June, and have both two and four stroke KTM's.
It is important whatever method of applying filter oil is used to make sure that the filter is completely covered (sometimes read saturated). The spray method accomplishes this just as well as any other method. You just need to make sure you have covered the filter inside and out with oil.

Big Lou,
Not sure if I invented something new here, or if this an old trick. I have begun using a cheap paint brush to "paint on" the air filter oil, I use Belray oil. Anyway, it is cleaner, you get better coverage without getting places on the filter that are soaked and other bare. You also seem to use much less filter oil. Also, if anybody could relay how spray on filter oil works compared to the oil, I would appreciate it.
Thanks
