New Throttle Cable Installation


Recommended Posts

A huge thanks to SMSgt for this excellent article. Kent did a great job and it is much appreciated.

 

Installing throttle cables on a Royal Star Venture.

I did this project while I was doing a change over from RSV handle bars to RSTD bars.

As with most jobs on the RSV you will need to remove the driver’s seat and gas tank. This not only protects the tank from damage but gives you access to the throttle/cruise control pulleys.

After you have removed the tank remove the black plastic left frame neck cover then you will have complete access to the throttle cables and clutch hydraulic line.

If you are doing the clutch it will need to take off the left side lower fairing and to take that off it will easier if you take off the right lower fairing as well. To make your job easier take off the left air cleaner and the mounting bracket.

As far as break and clutch hoses are concerned it is a simple remove and replace. You will need to bleed the lines. If you don’t know how to do this you might seek a little help from your friends.

Remove the clutch and front brake master cylinders. This is necessary to access the screws that secure the front controls and if you are doing a bar change you will need them off anyway to reinstall on the new bars.

 

Once you have removed the master cylinders you are ready to split the throttle handle bar control/twist grip.

Remove the two screws securing the right handle bar control/throttle twist grip. It is easiest done with a stubbie phillips screw driver. Sometimes a long screwdriver will not fit between the fairing and the screw. I replaced my phillips screws with allen screws because they are less likely to strip out while loosening them.

This is showing the right control split.

You can take the aft (the half with the stop switch on the top) apart by just taking the wire bundle out of the slot on the side with the cables coming out of it. This will give you more working room.

With the control split you can slide the twist grip and all off the handlebar. If you don’t have enough slack you can loosen and rotate the handle bars down this should work for you if all else fails you may have to take the handlebars off.

Once the control is off the bar you can lift the grip up and out of the control giving you access to the cables. Simple rotate the cables to the slot and it will come from the grip. Note, I hadn’t separated the two halves at this point

Once you have both cables loose you should feed them around the front of the triple tree so they are on the left side of the motorcycle.

On the left side of the motorcycle you will find the pulley assemble for the throttles and cruise control cable.

Slide the plastic cable guide back to give you room to work on the pulley assembly. It is the same kind as on the handlebars it should just slide one direction or the other then back.

With the cable clamp pushed back and cables pulled to the left side of the motorcycle the pulley assembly will lay over without any trouble. This will expose the screws and make it easier to work on the cables.

Remove the two screws that are now on the top of the pulley case. (Picture shows screws already removed.)

Opened cable pulley case. The Cruise control is the pulley on the top.

Another view showing the inside of the case. The one cable end in the front of the picture is the cruise control cable. Be careful not to let the spring not zing into space.

Lift up on the single piece of spring and the other end will come off and not be any problem. You will be able to see how it comes out once you look inside the case.

The hook end of the spring goes on the bottom, next to the pulley.

Inside of the cable case without the spring. The blue arrow is pointing at the place where the spring end will set when it is together. The red arrow is pointing where the hook end of the spring goes against the top pulley. Remember this is the cruise control pulley.

With the cruise control pulley removed you can see the cables going toward the carburetors and handle bars.

The two silver buttons are the cable ends for the throttle twist grip. Make sure you put the return in where the return cable came from and the pull where the pull cable belongs. This isn’t hard if you just pay attention.

Remove the screw and bracket that holds the return and pull cables going to the throttle twist grip.

This shows the screw and hold down bracket and the throttle cables going to the top of the last two pulleys in the case.

Remove the cables one at a time so as not to get mixed up.

Wrap the cable around the pulley the same way it came off.

Remove the return cable and install the new cable the same way the old cable came off.

 

http://www.venturerider.org/cables/cables_files/image043.jpg

 

Hold the new cables completely in the cable indentations.

Install the clamp and screw with the cables completely against the indent.

With both cables in and secure you will need to put the top, cruise, pulley in place. There are notches in the lower pulleys shown by the arrows and on the cruise control pulley shown by the small white squares inside the pulley. Make sure they are aligned correctly so your cruise control will work when you are done.

This is the bottom of the cruise control pulley. The arrows are pointing the notches that will go inside the notches in the lower pulley. Put the pulley in so at to allow it to pull the throttle open when the cruise control is set.

Showing the cruise control pulley in place. Notice position of cable end. It should be about the same position as when it came out.

Spring in place on pulley. Note position of “hook” as it fits in top pulley.

Spring pulled around to stop.

Cover back in place. Don’t forget to put the screws in.

Replace all the parts you have taken off in reverse order and go for a ride.
