Internal Cage and Foam Filter Installation

Twin Air saw the shortcomings of the XR 650R air filter and worked with the XR racing legend  Scott Summers' father Wade, to design a filter that would stay in place while putting the side cover back on.  The new air filter they came up with uses an internal cage to angle and hold the filter in such a way that it stays put and it also eliminates the backfire screen that lives behind the stock air filter, by using a three-stage filter with backfire foam.

Similar to the two-stroke filter systems, tacky oil traps dirt particles in the three stage filter. With this system, cleaning the filter is a breeze. Best of all - it doesn't fall out!

We've been using the new Twin Air cage system on our 650R for a few months and have noticed some performance gains. According to the GPS mounted on the handlebars our XR now pulls a solid 99 MPH as where it would only run up to 97 MPH with the original filter, it also seems to get to the top speed quicker. A small feature we noticed and were especially pleased with, was the snug fit that allows virtually no dust or junk to sneak by the outer edges of the filter.

Twin Air has been in the air filter business for more then 30 years and has come up with a system to make their air filters last longer and keeping them clean.  If you've been using gasoline and a washing machine to clean your air filter, you should have your head examined.  Besides making your clothes smell funny and pissing off loved ones, an explosion is eminent.  To do the right thing, you need to spend some cash, but it will make cleaning your air filter a job that isn't all that bad.  Included in the ?System? are: Liquid Power (filter oil), Liquid Dirt Remover (filter cleaner), Cleaning Tub/Cage, Oiling Tub, Contact Cleaner and Gloves. (The gloves are a nice touch to keep your hands clean while doing your filter business.)

I've been using the system on all of my bikes since I discovered it back in 1999, the thin filter oil doesn't fall out of the filter and become quite tacky.  When it's time to clean it, the Dirt Remover makes cleaning a quick and easy process, just pore the remover into the tub, stick the filter in and scrub, then wring it out.  Now flush it with some water and Voila! Your filter is clean as new.  To re-oil the filter, just submerge it into the tub with the liquid power oil, wring it out and you're ready to roll!
