    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.

Is it me, or are the instructions in the service manual confusing on doing this procedure.
 
It could be you or the directions what seems to be the problem ?
 
I am a little confused at where I set the gap. For instance the first step says to set the gap for the nos 1&4 points. When? When the mark is at F 1~4? OK, I set the gap, But then the next step says to move the plate CC until the points just start to open. Well they were already open.:confused:

And what is the difference between TDC and BTDC?

I'm doing the same thing on my 78 1000 right now. I believe the manual says to start with the l/h side points first (1&4) rotate until they are at the widest gap and set it to .035mm. then rotate the engine again with the test light or meter connected and find where they just open at. The fixed timing mark should now line up with the mark just to the left of the F 1-4. If not adjust by moving (rotate) the whole plate with the screws at 12, 4, & 8 oclock. Same deal with 2&3 except to adjust point opening position you move the half plate on the r/h side of the assembly and you use the line to the left of F 2-3. Loosen the screws just enough to move the plates, always rotate clockwise, and check it a few times. Hope this makes sense.

Thanks a lot, makes sense now!
 
I set them up correctly, but one does not spark at all. They are worn, time for some new ones. And yet again I have to order more parts, and wait for them to come in. :( But, in the higher rev range, it did miss some every now and again on 2&3, so I suspect, that this set of breaker points was intermittent. So with new points, hopefully she will not hiccup at all.
