This should apply to all Airheads from 1977-on, non-cooler equipped bikes. For the RS/RT bikes in this category, access to the filter cover might require removal of lower sections of the fairing and/or removal of the header pipe. In some cases I've heard that the header pipe might be dented, but I think this was to allow the original long filter to be more easily removed.
BMW had a bullet-proof filter system before the /7, but decided to "rethink" things! There is one critical decision to make regarding the thin metal shims and gaskets which will become apparent as I get through this. This won't be up to Brook's quality, but I thought it might be good to show the steps and what an owner might face. Oh, and do look past the dirt "patina" I seem to have accumulated.
Here's a picture of my kit and tools used for this filter change...the kit is part number #11009056145 and contains the following items:
- filter -- #11421337570 ("bendy" filter is probably less likely to collapse versus the original straight filter)
- washer/shim -- 11421336895
- o-ring -- 11421264160 (was -098 per RealOEM)
- gasket -- 11421338600
- crush washer -- 07119963300
I use an extra gasket which will be discussed later.
From the tool kit, I needed the 10mm wrench along with the 8mm allen wrench. My oil of choice for the moment is Golden Spectro 4 20w50. Refer to March 2013 Owners News for the latest test on various grades of oils for the Airhead engine.
