Choke Modification

In an attempt to remove more wires &
cables from the handle bars, I moved the
choke activation assembly below the right
side of the tank. This modification was originated
by HARMSIE. I followed his idea and instructions
to complete this modification. I used lots
of photos, so it may take a minute to load
for you poor unfortunate dial up folks. I
feel for you! The modification is simple
and straight forward. It took me about three
hours to complete the entire project.
However, if you are going to run wires through
your handle bars, be sure you do this modification
first. Otherwise, like me, you will have
to modify (cut the thumb push off and sand
smooth) the original choke knob instead of
replacing it with the adapter listed below.
The following chart is a list of the parts required for this project. The cost are from www.servicehonda.com. I do not guarantee the prices to still be accurate. Contact them to find out current cost.

| 17950-MBA-000 | Cable Comp, Choke | 1 | $22.34 |
| 17962-MR1-000 | Adapter | 1 | $8.57 |
| 12295-MBA-000 | Stay, Choke Cable | 1 | $2.48 |
| Total: | $33.39 | ||
| 6 mm bolt | 1 | $0.00 | |
| 6 mm nut | 1 | $0.00 |
1. Remove the seat.
2. Remove the gas tank. Be sure to turn off
the fuel, remove the fuel line, and remove
the vent line before attempting to lift the
tank off.


3. Remove the right side frame cover.

4. Disassemble the left side switch housing.
Remove all of the electronics from the bottom
half. All of the pieces are held down by
small screws. Disconnect the choke cable
from the black plastic choke knob. Unscrew
the choke cable from the lower half of the
housing.

5. Remove the left grip from the handle bar.
Slide the old choke knob off the handle bar.
Slide the new adapter (17962-MR1-000) onto
the handle bar. (My adapter came in gray
so I painted it black with spray paint. Use
something that will stick to plastick) Re-assemble
the electronics in the lower half of the
switch housing. Put the switch housings back
together with the adapter in place of the
old choke knob. Align the tab on the lower
half with the hole in the handle bar. Put
the left side grip back on the handle bar.
Now, doesn't that look nice! However, a lot
of work is yet to be done.
6. Gently, pull the end of the choke cable
through the right side frame cover.

7. Remove the choke cable from the carbs.
This is done by unscrewing the black plastic
piece from the carb. Gently pull off the
rubber 90 degree boot that covers the plastic
piece. It will slide off and give you better
access to the plastic piece. Then remove
the needle and spring from the cable. It
will fall off if not carefully handled. The
plastic piece will also come off. Do this
for both sides. (On the left side, there
is a bracket that holds the cable near the
frame. Gently push the cable out of this
bracket to provide some slack in the cable.
Don't forget to put it back in the bracket
during installation. It appears that the
cable might interfere with the throttle if
not held in place. Can't have that!)

8. Remove the choke cable mounting bracket
from the right side frame. The bolt is beneath
the wires. Then take the choke cable out
of the bracket.

9. The large section that was held by the
bracket is a plastic tube. Inside the tube
is an adapter that connects the two cables
coming from the carbs to the single cable
going to the choke knob. Roll back the rubber
boots on the carb side of this tube. It should
turn inside out on the cables. Pull the black
plastic tube from the cables. They just snap
together. Inside the tube you will see the
white plastic adapter with three cables attached
to it. Remove the two carb cables from the
adapter and set the knob side cable somewhere
out of the way. You are done with it.

10. Disassemble the new choke cable assembly.
It is slightly different than the stock Sabre
piece. Roll back the rubber boot that is
on the knob side of the plastic tube. The
end snaps off the tube. Slowly pull the pieces
apart until the white adapter piece is visible.
Remove the choke side cables from the adapter.
Set the knob cable down. Roll the rubber
boot back on the carb cable side of the tube
and pull the two cables out of the plastic
tube. Pull the rubber boot off the two carb
cables and set the carb cables out of the
way. They will not be used.


11. Remove the rubber boot from the two original
carb cables and replace it with the new rubber
boot.


12. Place the new plastic tube over the original
carb cables. Push the cables firmly into
place. Move the rubber boot over the plastic
piece to hold the tube in place.
13. The carb cables will need to be pulled
outside the new plastic tube so that they
can be attached to the adapter. To do this,
push the cable from the carb end as far as
possible. It will go up inside the rubber
boot. Using a needle nose pliers gently pull
the cable out enough to attach it to the
adapter. Do this for the other side, too.
14. Route the new knob cable over the front
cylinder and up through the frame. If you
look close in the following picture, you
can see the cable running over the front
cylinder.
15. Put a little grease inside the plastic
tube before proceeding.

16. Attach the two carb cables to the white
plastic adapter. Then slide the adapter into
the plastic tube. The cables will need to
be pushed back towards the carbs. Using a
small screwdriver, push both cables and the
adapter as far as possible into the tube.
This is necessary to re-attach the cables
to the carbs.
17. Frimly push the tube into the rubber
boot of the knob cable. It should not come
apart easily.

18. Re-attach the carb cables to the carbs.
Put the plastic nut, spring, and needle back
on the cable. Slide the needle back in the
carb and thread the plastic nut back into
the carb. Be careful not to cross thread
the nut. Push the 90 degree boot back on
the plastic nut. Be sure to put the left
side cable back in the bracket to keep it
out of the throttle.
19. Verify that the cables move freely by
pulling on the new choke knob.
20. Re-attach the choke braket to the frame.
Place the new plastic tube into the braket
and secure it with a plastic tie. The tube
is smaller than the original and will not
stay in the bracket.

21. Put the right side frame cover back on
the bike.
22. Put the fuel tank back on the bike. Reattach
the vent tube and the fuel line.
23. Put the seat back on the bike.
24. Mount the new choke stay (small black
bracket) (12295-MBA-000) on the choke knob.
The large black plastic nut on the knob unscrews
and the stay slides onto the knob and is
held in place by the nut.
25. Attach the choke stay to the tab that
is on the frame using the 6mm bolt and nut.

26. Start the bike and check for proper choke
operation.
