If in doubt, change your air filter

I know better.. I was too lazy.
My filter had one ride on it and was a little darkened but didn't need to be changed yet. I went riding again last Sunday and brought a new, oiled filter with me to put in.. I was too lazy. After having fun all day in the deep powdery silt berms, I got it home and washed it. I figure I'll change that filter now and take the bike for a quick ride to dry it off, right? Well, first thing I notice upon removal of the dirt-CAKED filter is silt. Silt everywhere inside the intake tract. Uh oh. The inside of the filter (Ready Filter) shows that no dirt got through the sealed edge, but right through the middle of it, about 25% of the surface area! I've never seen this before, but I don't think it was the filter's fault, it was mine for not changing it when it needed it.

Now I'm going to pay for it. Silt all the way through the intake tract. Silt all over the carb bell and slide. Pretty clean between the slide and the reeds, and then silt all over the back of the reed cage and the cylinder's intake port.

I pulled the pipe off and there is some minor scoring on both the intake and exhaust sides of the piston, but not too bad. I'll bet the bottom end loved all that sand.

The bike still ran fine when I shut it off so hopefully there is no harm done other than increased wear.

What's the best way to get all of that oily silt/sand out of the air boot?

I'd take the entire airbox assembly off the bike and hose it down repeatedly. FWIW I've heard a few of these stories about older versions of Ready filters.

Me too, thanks!

I'v seen the same happen with an older twin air. I think that over time filters might become more poerus. Be sure to clean it well before running it.

good luck
