WHAT STANDS OUT? Here’s a list of things that stand
out with the Sprocket Stuff countershaft sprocket tool.
(1) Design. If you want to replace a worn-out countershaft sprocket or change your gearing, removing the old
countershaft sprocket can be a hassle. It is typically
corroded in place, and when you try to turn the
sprocket, you typically turn the engine over (and the
sprocket doesn’t budge). Sprocket Stuff’s counter sprocket
tool is designed to lock your bike’s countershaft sprocket
to the swingarm so that it can’t spin.
( 2) Updates. The previous Sprocket Stuff tool had to
be ordered in teeth sizes. For example, if you wanted
to remove a 13-tooth countershaft sprocket, you needed
their 13-tooth tool. All well and good, unless you were
adding a 14-tooth sprocket in place of the 13, then you
needed their 14-tooth tool to install it (or remove it when
it was time to replace it). The new design now fits on
13- 14- and 15-tooth sprockets. All you have to do is move
the pins that slip into the grooves between the sprocket
teeth. Additionally, the new design is more compact so
you don’t have to remove your engine’s case saver.
( 3) Directions. In step one, you have to remove the
chain. Why? Because the pins of the Sprocket Stuff tool
have to fit into the teeth of the countershaft sprocket,
and they can’t do this if the chain is on the sprocket.
Step two is to bend the locking tab away from the
countershaft nut. Step three is to slip the Sprocket
Stuff countershaft sprocket tool onto the sprocket
with the two elongated arms positioned above and
below the swingarm pivot. The arms lessen side load
on the countershaft bearing. The final step is to put
the proper-size socket on the nut and turn it with a
ratchet or breaker bar. Sprocket Stuff does not recommend using an air-impact wrench for this job. To
install a new countershaft sprocket, you simply reverse
the direction of your motion. You can hand-crank it
into place or, if you are smart, use a torque wrench
to set it at the proper torque setting (found in your
WHAT’S THE SQUAWK? There are other homegrown
ways to remove and install a countershaft sprocket that
don’t require a $20 tool.
The Sprocket Stuff tool is a luxury item,
but then so are most specialty tools.
