I use the 4 inch fabric filter. I also it with a foam prefilter and outerwear. Are both the pre filter foam and outerwear necessary and if not, which should be used as a priority?

Slight coat of wheel bearing grease on the carb adapter will help stop some of what makes it through. We practiced one day and had a bunch of crap in ours and I started that ritual.I definitely agree with needing both. I found out that the outerwear by itself definitely does not stop fine dust, as my carb was covered inside. That is using a brand new, properly oiled paper filter, and a new outerwear.
Paper filters are better for dusty conditions? I have used them, oiled, and covered with an outerwear prefilter since April and noticed very fine dust at the intake a few times. Test and tunes when the track is just not prepped. Just recently went to K&N cotton filters still using an outerwear prefilter. Is there a significant difference and is one better than the other in certain conditions? Thought I was doing myself a favor with the K&Ns...
You should not be seeing any dirt (fine or otherwise) in your carb or intake. If it's ingressed that far, it will certainly be in the cylinder and rings as well.
You can't beat K&N for quality. On the typical kart filters, I have not seen their Remay material flow any better than the paper material when they are brand new. After a few oilings and cleanings though, the K&N will definitely outflow the cheaper paper element filters. The paper breaks down after a while.
Either way you go, unless the track is really clean, we put a fresh filter on each time the kart hits the track. Cheap protection for your valuable investment.
You don’t race where I do!dont need both, we always use just foams, if all we ran was concrete id use the outerwear
nope, dont race in dust bowls, that just shows the track owner either doesnt know how to get rid of the dust, or just to cheap not toYou don’t race where I do!
