    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.

Ordering a Colortune?, what size plug thread?

Hey all...
I'm wanting to order a colortune kit and don't have my manual here at my computer desk. What's the plug thread size on my 81 GS850GLX? The kit says it is a 10MM and that it includes a 14MM adapter. I just want to make sure I get everything I need.

Thanks! :)
 
Personally, I wouldn't bother. I got one to tune my MG, and found it to be useless. I could tune better by ear or with a vacuum guage than with the colortune. I tried it a couple of times and could never get it to work right. Just my 2 cents.
 
You'll be fine with the 14 MM adapter. I got a NOS unit on eBay, and it was for 14 MM plugs. I personally found it to be quite useful and easy to use to boot.

I use 5mm adapters that screw into the intakes where the allen bolt comes out.
