I'm using a dual inlet filter under the A/C; I have a second dual inlet always clean and ready to put on, I find they will become slowly oil saturated and don't work as effectively so when they begin to discolor I put on the clean filter.

I clean the breather filters with K&N air filter spray cleaner then rinse them in hot water and let them dry. Never any oil on the bike or exhaust that way. Remove your breather filter and give it a good bath and you'll be good to go for a while

I used 1/4" (6.35mm) fuel hose and just a cheap filter I found on Amazon that would fit with the connectors I used.

I like this filter. Uni Up-122. Its small and has the zip tie loop so you can hide it anywhere easily. You could hide it right between the heads somewhere.

[QUOTE=esteboatan;16312914]I got my ideas from the thread linked to a few posts up. I made my own set up with a few connectors, tubing and a filter. It was very easy to do.[/QUOTE

So the 1/4" ID fuel line is just "pushed on" to the breather bolts, and it stays on OK?

What are you doing to seal this void (path) to the Outside World? Your air filter element won't help you there.

I use small red connectors that clamp onto the tube and the socket thingy. It stays tight. Needle nose pliers are required to clamp it into the space.

I use folded tubing (3/8" OD) and zip tie the ends after its bent, its a nice tight fit. No air is getting in through the holes.
