Throttle Cables... Do we really need 2?
I know for legality reasons, street bikes are required to have a push/pull throttle cable arrangement, which our bikes does have.
My question... Can I get rid of the "push" cable and not suffer ant ill effects? I've done this to my single cylinder CV carbed dirt bike and have had no problems. Has anyone done this and have you run into problems because of this? Why remove it?? One less cable to adjust, one less failure point, less weight. |

While you're at it, make sure to remove the cotter pins on the front and rear axle castle nuts; that's good for another 5 - 6 grams.

That's the key right there
I don't have any experience with this on bikes, but from my experience with small bike engined cars we only ever used one. As long as there is enough return force in the springs you should be ok. I guess just another reason to make sure your cables are in good shape and clean. |

It's actually not a legal requirement. Some Ducati motorcycles, even recent ones, have come with only single throttle cables. But doing the mod on a bike that came with a push/pull setup doesn't seem wise to me. Of course it's OK as long as nothing happens with that single cable that's left. And in the scheme of things, having the throttle do something unexpected (or not respond as expected) on a ninjette is probably much less dangerous than on a literbike. But I don't get going through the trouble to simplify the maintenance (takes 2 seconds to adjust both cables), or the weight (inconsequential). Heck, weigh a Corbin seat and a stock seat, and see whether it's necessary to remove 30 or 40 throttle cables to make up the difference.

I find it quite a pain to get the cables adjusted correctly and if you have one correct and the other incorrect, the net result is that it's out of adjustment. The worse that could happen if the single cable breaks is that the bike will go back to idle... the same in a push/pull setup. I'm looking for reasons for why I need to keep it that may affect the bikes proper operation or ridability. From the reasons you stated, you're keeping it just cause it's there. |

Removing one cable means there's one less safety net. And even in a non-critical situation, it's one less component that may be used to idle the bike home carefully (if we notice one cable has snapped but the throttle is still mostly usable with one left). We can debate the likelihood of any cable (or return spring) failing under normal usage, but these types of things are designed for that 1 in a 1000 shot, not because it's expected to happen on 9 out of 10 bikes. From the reasons you've stated, you're considering modding it because you have run out of other things to do to the ninjette.

I think this is a more plausible answer as to why most bikes have this crazy setup... (found on the web) I did find out that some time ago that Honda was in a law suit and lost because of a throttle stick(single cable).After this it seemed that the dual cable came out and everyone jumped on the band wagon. If a throttle would ever stick it will be because of lack of maintenance. |

And these cables were spec'd for a bike that the designers knew would have two of 'em. I wonder if more care is put into the cable design (thickness, materials, and attachment points) for bikes that don't use the push/pull setup. Even the new Yamaha throttles that are running an electronic sensor to measure throttle activity and a stepper motor to control the throttle plates still have both a return spring and manual cable in place to positively confirm that the throttle plates are closed when the rider rolls off.

It needs zero yet has one. Just like us needing one and having two.

To me, and maybe only to me, this seems like the Harley guys opposing ABS not for any philosophical reason other than the cable running to the front wheel and the small disk, so Harley had to design a completely invisible system for it to be accepted with the magnets in the carrier bolts. We take enough risk as it is deciding to hop on a bike instead of taking the car; removing safety measures on the bike for aesthetics alone isn't a path I'd choose or recommend.

And again, look at my original post. It was asking if removing the push cable affected the operation of the bike or caused problems. Whatever views you hold on how safe your bike needs to be before you jump on it is a personal preference and you are certainly entitled to your opinion.
So, if I run with only one cable... you gonna be okay with it? |

Only time I didnt use the push/pull cable is when I swapped out the stock carbs for CR's. I was just being lazy & not hooking up the second,,,, Never really worried about thou. If any carbs needed two, I would think that type would before a CV type.

Not only do I believe in the redundency of two throttle cables, I threw another one in there JUST to be safe!

so what difference would it make if it's one or two cables connected to do a job that it doesn't do in the first place? not trying to be a wise ass... just trying to make sure I won't run into a problem if I take the push cable off to experiment.

I honestly have no idea if you can go with just one cable; out of all the bikes I've owned, I've never even lubed a throttle cable or had one break. Hard for me to imagine why you would even think about removing one Kelly, but guess you are just looking for ways to save weight when you get here next year to race one of my bikes

I'll be installing a quick turn throttle shortly and debating about removing the extra cable while I'm in there. |
