    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.

ND or KD

ND vs.KD

ND vs.KD

ND is Nippon Denso, which I believe made most of the ignition systems on the GSes; I know my '78 GS 750 is ND. Maybe someone elso out there can enlighten us. Guys?
 
I think it's nd as well but not 100%... hoped someone could clear this up for me.
 
found this and copied it from another thread :

"Also, the two types use a different rotor, and they are not interchangeable. The mechanical advance unit make you use will determine the dyna style you need, either ND (Nippondenso) or KD (kokusan) Ask which it is when you buy one Mechanical advance units for ND systems used points held to the breaker plate with one screw. Advance units for KD systems used points held to the breaker plate with two screws."

can anyone verify that this is correct? Thanks again.
 
I pulled a set of points out of a kit for my 77 750, with ND points. They are not the same as yours. MY 78 550 has the K variety but I do not have a set in the house and it is too cold and dark for me to go exploring tonight. I believe they both have 1 screw.
 
Go to www.z1enterprises.com. Best price in town for the Dyna-S

Two types of Dyna-S systems available for Suzi's, the DS3-1 & the DS3-2. Here's a link for the -1, with instructions on how to check your bike for the type of ignition you have.

http://www.z1enterprises.com/detail.aspx?ID=1308

It says:
1977-78 GS550 & GS750 bikes, some of these models came with a ND ignition advancer, for these bikes a different Dyna-S is required. How do you tell? Take off the points cover, the ignition advancer should be stamped with KD (Kokusan Densi) or ND (Nippon Densi). If you have a ND unit, see the DYDS3-2.

Hope that helps.
 
Thanks guys for all the info. I think that mine are KD... and the fact that rgierer has ND and single screw versus my dual screws verifies my suspicion. Thanks Tom for the link... I actually already read that at z1 but I couldn't find the kd/nd stamp anywhere. I had previously changed the points so these could be after market or something. Thanks guys as always.

just read that Jeff.. thanks for the links... my points are deff.. KD thanks again

Just bought the S system today... can't wait for it to get here... didn't know z1 was located in NY, had to pay 8% sales tax. Hope a % of those extra 10 bucks goes into improving some of the roads around here... lol Thanks again guys for all the help.
