to mount the new ones.
The JRi shocks are beautifully
made, and when comparing them to
news is the ride is noticeably better
than expected, no bottoming out and
very smooth and predictable through
the turns. The bad news is the rear
shocks are so very good, the front
suspension now really stands out as
lacking. However, I hear JRi is now
also making high-end fork cartridges
for Harleys. Unfortunately, not yet for
my year Dyna.
JRI SHOCKS come pre-adjusted,
but to achieve the maximum benefit
TIPS &
TRICKS
from your new shocks
you should set the sag.
First, mark a location on
the rear subframe directly above the
axle centerline. You can use a small
piece of masking tape. Raise the
rear of the bike until the wheel just
comes off the ground, and measure
the distance from the axle to the
subframe, this is measurement A.
Then have the rider (with gear) sit
on the bike and measure again, this
is measurement B. Subtract B from
A and this is your total sag. It should
be between 25mm-30mm. If greater
than 30mm, add preload to the
spring. If less than 25mm, remove
preload.
2
Jack up the rear of the bike to get the weight of the
vehicle off the shocks.
5
Install the new JRi shock using the stock hardware. Install
the lower bolt first, but do not tighten completely,
as the shock may need to be pivoteded to align with
the upper mounting hole.
7
Once both sides are done, lower the bike back to terra
firma.
3
Remove the lower shock bolt (one side at a time) with
a T50 torx socket wrench.
4
Loosen and remove the top shock bolt with a 3/4"
wrench and remove the shock absorber.
6
Then install the original upper shock bolt and tighten
with a 3/4" wrench. Then tighten the lower shock bolts
with the Torx T50 socket wrench. Torque the upper
bolts to 75-85 ft-lb. Torque the lower Torx bolts to
30-40 ft-lb.
8
This black and blue knob is the bleed adjuster. There
are 40 clicks of adjustment. If you have harshness over
bumps or wallowing while exiting a corner you can
adjust the shock. Test ride and tune in small increments.
