If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

What kind of throttle cable do I need?

  • Thread starter Thread starter freedwilly
  • Start date Start date
The older Suzuki's with VM carbs all have 2 throttle cables so I would look for cables from something prior to 79.
 
I still want to know why they call those setups Push/Pull when they obviously don't push anything?

BTW, I think you only need to use the "Pull" side.;) Seriously, just one cable, not two.

HAHA yes I agree. Only reason I came up with for calling them that is because when you pull the bike is pushed... definitely a stretch though.

Any good sources for a cable that would work with that set up? Or suggestions for a better setup?

NO! You need two cables (push&pull) on VM Carburetors!!! The slides may not come down after a wide open situation... Remember when Rapid Ray schooled us on the subject? I know we were talking about 29mm Smooth Bores, but I think the rule applys to all VM type carburetors. Just buy the second cable. 👍

Absolutely NO argument, Norm. :encouragement:

Now take a moment to consider that the guy is asking about his 1981 GS450. :-k

All GS bikes came with BS-series CV-type carbs from 1980 on.

Not only that, but I belive that all the twins had CV-type carbs from the beginning, in 1977.

He only needs one cable. :-\\\

They are NOT push/pull cables, thy are pull/pull. they pull the slides up and pull them down again.
You only need the one cable on VM carbs as they have a hefty return spring to pull them shut.
Been running single cable on my GS1000 for years, running VM28's and VM29's with no issues.
 
Beating dead horse...

Isn't pulling something down physically equivalent to pushing something down? The location of where the force is applied may be different but the direction is the same. So instead of pull up and pull down, you can simply say push/pull to indicate force is applied in both directions.

A FWD car pulls the car and a RWD car pushes it. But they both go the same direction.

So, what about a four-wheel drive or all-wheel drive? Push-pull?

Yes, in some cases, you can push with a cable, but those cables are usually more rigid, much like the controls on a radio controlled airplane. The control cables that I have seen were thin, solid wire inside a sheath. You can anchor the sheath and use the inner cable to push or pull on the control surfaces.

The cables on MY motorcycles are far too flexible to push anything. The second cable on the VM carbs is PULLED by the other side of the throttle grip and it, in turn, PULLS on the other side of the bellcrank on the carbs.

Sorry, but it's a PULL-PULL system.
