    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 coils be fixed?

I have 2 sets of OEM coils for my '77 GS750. I recently discovered that I was getting an irratic spark over about 5000 RPM. So I installed my other coils and the problem went away.

I like the idea of having a spare set of coils so I am wondering if the bad coils could be fixed. Here is what they do: I put the timing light on the sparkplug leads and observed the timing light; above 5000 RPM the spark is irratic. Below that engine speed the spark is regular. Could this be bad leads or end caps? How do you change leads?

Thanks

Hi,

As far as I know the ignition coils are a sealed unit and cannot be repaired. The plug wires can be replaced with a little effort. Dig out the old epoxy, pull the wires, then epoxy new wires in place.

The spark plug caps can also be replaced very easily: Spark Plug Cap Replacement


Thank you for your indulgence,

Thanks BassCliff, I think I will replace the leads on 1 of the coils and see how that works.
