Suzuki 2 Strokes

Yet another post about air filters...

So I've had cone type, paper element, and shorty cones of 2 different varieties. Trying to get some feedback on what you guys have tried that has performed the best, or most closely like the performance of a stock air box. I went up a size on both jets when I switched over to the pods and the bike does now run a bit rich, so I'm considering returning to stock jetting but I realize that there's a fine line between safe and unsafe.

Was thinking about some foam elements.

Thoughts?

Thanks again guys!

Would love to hear the answer on this also as I'm doing the same.

The two makes of filters that seem to have the best following are K&N and UNI. I use 6" long UNI filters (oiled) to give the largest available area of filtration and the lowest resistance to flow. If I want something close to stock, I replace the stock old filter with UNI filter foam of appropriate thickness.

I seem to recall tests in a UK magazine where they tested the time to clog small and large particles (filtration ability) and flow/pressure drop and all manner of other variables and it seemed to me that the filters that had least resistance and best flow were not so good at filtering and the ones that filtered really well didn't flow all that well.

I'd like to see an update on those tests.

In the absence of hard data I'd go with anecdotal evidence that suggests that K&N and UNI are "best"

What is it with the UK, and studies that have an obvious answer? Cover your carb inlets with 5 layers of thick aluminum foil, and airflow is bad, but it keeps the particles out. Use some torn cheesecloth, and it flows great, but sucks in small rocks.

I saw another study out of the UK, where they tried to answer the question of why guys fall asleep after sex. Their answer? We're tired.

It wasn't quite that obvious. Some filters were very restrictive to airflow but still managed to let all the fine and coarse dirt through.
