1) Raise the
motorcycle with a bike stand, milk crate, etc., so the rear wheel is
slightly off the ground.
Remove the 17 mm nuts from the two link mounting bolts
and push the front one out
the right side and the rear one out the left side. The
swing arm may need to be
raised slightly to allow the bolts to slide out freely. After removing
these two bolts the link will drop out the bottom and your about ready
to install the new link.
2) The new links come
with the bearings and seals, so put a little grease on the two needle bearings
first, and then install the "center sleeve" from your old OEM link into
the new link. You are now ready to install the new link by holding
it back in place with the bearing end forward and the engraving readable
from the right side. After aligning the link eyes with the link mounts
push the mounting bolts back through. You will need to raise the swingarm
to get the eyes to line up. Front bolt goes in from the right side
and the rear bolt goes in from the left side. Install the two 17
mm nuts and torque to approx. 35 lb-ft.
3) After installing the KoubaLink,
be sure the 90 degree grease fitting is facing down. *Left side engraving
will be upsidedown. May want to pump a little grease into that
grease fitting now so you don't forget.
4) For the 1.5"(CRF150) or
2"(CRF230) rear lowering, set the race sag (amount of vertical movement
of the rear axle FROM no weight to bike weight plus rider weight) at 2.75"
with rider in full riding gear, standing on the pegs. This sag adjustment
can be changed by turning the two large nuts on top of the rear spring.
(More preload = less sag, and less preload = more sag. Turning the spring
preload nuts clockwise will increase the preload and visa versa.)
The easiest way we have found to change the preload adjustment is to loosen
the top jam nut, lube the threads on the shock and turn the spring and
all by grasping the bottom of the spring. It will turn easier if
the rear wheel is off the ground.
5) The front fork tubes can
be slid up in the triple clamps past the handlebars, but we do not recommend
over 1.0 inch of the tubes showing above the top triple clamp as we are
not sure exactly when the front tire would be allowed to contact the underside
of the fender when fully compressed. :-( (The owners
manual says it has 8.5" of front wheel travel.) If the front pushes
or will not turn quick enough we recommend lessening the rear sag rather
than sliding the fork tubes up farther than the 1.0" Disclaimer:
Lowering the rear more than the front can change the geometry and could
affect the handling, so be careful out there.
