    I want to do a 1 to 2 split for my throttle cables, is it possible to do it safely on my own or is it something that needs to be done in a pro shop?

    Doing it on a R75/5 with Bings..

    I was looking at the splitter junction box and it seems pretty strait forward but I'm not so sure how the cable ends are applied to all these cables. Crimped, soldered, screw clamp..

    thanks, any info would be appreciated.

    Off the shelf from places like Motobins. The 81 onwards machines had splitters as standard. They just take a few minutes to fit but you may want the right throttle cam and single outlet throttle assembly.

    Whoa, thanks.

    Rob I have a nice tommaselli single pull throttle all ready to go. I hope it will do the job.


    cathouse, thats a helpful little vid... if he used a denser wood he would have better results on finish.. I have a chunck of Ipe I'm going to test it on.. It should give a smoother surface when pulled out.


    Thanks guys.

    this was the splitter i was looking at.

    Looks a little short. Make sure it won't limit your cable pull and not allow you to open up the throttle all the way. Figure out how much cable take-up it takes to get the bings all the way open and add a bit for free play.

    You can do it!

    The spreading/peening of the cable end is the most important point of all. Without that the joint will fail, even on a throttle cable.

    32 73 1 242 014 x1 splitter 16.00
    total $73.00

    You might have to modify the exposed length on the upper cable if you are using the /5 throttle assembly.

    Would anybody mind explaining why this conversion is a good idea. I am planing on replacing my cables soon.

    If you are installing new ends on a cable the right way is to use a solder pot...but a 1/2" black iron pipe cap with a propane torch for heat works great as a makeshift one...have done it this way successfully using plumbers solder and flux. Before I knew better I tried soldering directly with a torch and the cable failed quickly.

    I converted mine, because (IMHO) dual cables running all the way to the throttle grip get tugged, and pulled when turning the bars, and such causing them to get out of sync with each other more quickly/easily.
    By running one cable as far down as possible, only one cable bends with turns, keeping thing in sync with each other. I also think there is slightly less drag, due to the lesser amount of cable being pulled.

    Dual cables are easier to deal with and less maintenance. If your having problems with cables pulling or adjustment staying either run longer cables or route them in a smoother path. Stick with the dual cable set up.

    I'm going to try this with your pipe trick, or rather a pipe end cap... Looks like the way to go.


    What splitter box are people using, out of curiosity?

    Also I've seen a fitting that is a curved tube between throttle body and cable to divert the cable to a 90ish degree angle... it it ok to use one or is it considered a no-no?

    I'm not using a /5 throttle, its a Tommaselli super praxis... is what its called.. i think.

    This is exactly what I need... Is there an issue with the splitter being plastic... was reading around and saw in the descriptions of others that a metal one was an better idea, but was wondering if its just a solution to a non-issue?

    The plastic one works fine and it's cheap. Make sure to grease it.

    good deal, worked well for me. Once the solder is melted in the pipe cap it stays molten for quite awhile so you can take your time dipping the cable ends....in my case the flux boiled away in about 10 secs. as Flanders suggests The molten solder could be dangerous if it was spilled so I clamped the pipe cap in some vice grips which in turn were clamped in a vice
