Step 2c Install the supplied wide band oxygen sensors
into the exhaust pipes. If your exhaust system is not
equipped with oxygen sensor bungs, they must be
added to the exhaust pipes. The supplied wide band
sensors are longer than the factory sensors. Installation
of the wide band sensors into factory headpipes
equipped with bungs should present no clearance
problems, however, some aftermarket pipes may require
exhaust pipe modification or sensor bung relocation for
interference-free installation. The sensors must mount
freely without contacting surrounding components. If
this is not possible, do not attempt to bend or
modify the sensor in any way as it is a sensitive
electronic component and will be damaged if you do.

are available for exhausts systems not equipped with
bungs or if current bungs present clearance issues.
Bungs should be located no more than 3-4” from the
head/pipe connection (for ideal location, refer to the
factory location on 2008-up models). W eld-in bungs are
available from Zipper’s (#272-200, straight; #272-202,
angled). After installation, route the sensor harnesses
through to the left side of the bike as shown.
