I have a 2013 YZ250. I think the air box is small because I have to turn and twist the filter to get it out. While doing so, it appears that tiny bits of dirt get down in the boot. Usually when this happens I'll take the whole subframe off and clean everything up. However, I'm getting tired of that. Plus, I don't think it is good on the bolts and anchor nuts and such fastening the subframe, number plates and silencer to the bike to be going in and out so much.
So, I'm seeking advice from you gurus of dirt. Do I need to be concerned with a few small grains of sand in my air boot? How do YOU handle this? Lately I've taken to washing the air box out with VP soap with the dirty filter still in place. This does help, but is not the perfect solution. I bought the Twin-Air cover to use when washing the air box out, but that doesn't fix the problem because the problem happens when removing the dirty air filter. Am I over-thinking this? Should I just get a vacuum with a small hose that will get in the boot?

of the air box. Try popping the filter off and just move it back far enough to allow you to slide that nifty Twin Air cvr in place.
You can just hold the cvr in place while you remove the filter. Once the filter is out of the way, you can thread and tighten
the wingnut and go to town cleaning the inside of the airbox.
Got to love that FL sand!

Dogger, you KNOW that Florida sand! Even after washing my air filter in Oxy and then Dawn dish soap and hot water, it still holds very fine sand. After it dries out I can take it and use compressed air to blow out the very fine stuff. It really is something. It is white and very fine-grained - much more so than beach sand. Amazing stuff!
Unfortunately, I am all to familiar with that sand. Have you tried those filter skins? Might help lessen the amount of sand
that can work it's way into the main filter.

PS. Still loving the Redline oils. QUALITY all the way. I know you said the gearbox oil is a bit over the top for this slow, old guy, but man that stuff is awesome. Besides, even though it is $16 a quart here, I've noticed it only needs to be changed a third as often as other oils. The premix is incredible. It stays mixed and never ever gives me anything but a clean cylinder and piston on tear down.
Also use some small vaccum attachments. But some times it does require r&r to clean right. I too will try laying it in the side
Too simple!
Taking all the stuff off only adds a few minutes to the job. The actually filter cleaning/oiling process is the part that I hate, but I've found that I can push service intervals to 5-6+ hours as long as I use Belray or Maxima liquid filter oils. That means I typically do 4 prepped track practices on a filter.
With Maxima and Belray, you can have a 1/4" of dirt built up on the outside of the filter and it will never pass thru, no matter how long the bike sits up. The bike just runs progressively richer as the filter becomes more restrictive.
You're right, the Bel-Ray oil rocks. Nothing passes through. I am really intrigued by the ease of the no-toil system but keep hearing that it just does not stop dirt as well.

You don't have to use fresh solvent every time. I use the same solvent over and over and add a little diesel when the level gets low. About once a year I will strain the old diesel through a paper paint filter and collect all the solids in a metal coffee can, which gets collected by the city during their chemical disposal day.
If you are religious about filter maintenance before every ride, no-toil is a good system. I have too many bikes to maintain to be servicing filters before every ride.
