    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. 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.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. 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.

Can I make a shift linkage?

I have a gs1100 shift linkage I need to make longer on a Frankenstein project. Does anyone know the thread pitch for the linkage? I know one side is left hand thread all I've found is m6 was thinking about getting some round stock and cutting to length and threading both ends. Seem easy enough instead of trying to weld a piece in the middle and make it straight plus I don't have a welder easily accessible.
 
The threads on the ones I've seen are M6 diameter X 1mm pitch, standard thread, but one end is left-handed.

You can get M6 rod and a left-hand die (and a right-hand die, of course) at McMaster-Carr.

M6 Steel rods:

Left-hand M6 die:

You can also buy M6 linkage rod in various lengths already threaded. Google "M6 linkage rod".
For example: https://midwestcontrol.com/shop/TR6-500

Or haunt a motorcycle junkyard for a bit. Most Japanese bikes used linkage with the same threads.

Dime City Cycles also has various linkage bits and kits that might be what you need. Scroll down to "related products" to see more:

Awesome thanks that's exactly what I needed! I would hit up the local junk yard but there's not one in the Kansas City area so I resort to ebay hahah. I'm thinking of going to the local fastenal and seeing if they have what I need.
 
Fastenal's website doesn't list left-handed M6 dies or linkage rod, so I doubt you're going to find anything there you can use, unless you want to cobble something together with 1/4" stuff. They do list M6 rod ends, but they're over $50 each.
 
You can make an extender out of a coupling nut and a piece of all-thread or a cut off nut. Just JB Weld the bolt piece halfway down into the coupling nut.

Edit: Just to be clear, I meant a "cut off bolt". I'm sure y'all figured out what I meant.

Good thinking, just extend the right hand thread side!
I will take note of the left hand thread M6 dies from McMaster, however...
