    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.

Coil, wires, caps?

Gents:

1979 GS750L, being transformed into a cafe racer style bike.
But staying stock as possible in most areas, for ease of maintenance.

Coils:
Tested them last night, and the primary and secondary is shot on one, secondary on the other.
Bike runs on two cylinders.
One plug cap resistor was nothing but ashes. Others look fine.
One coil got very hot. One got slightly warm. (?)

Question:
Buy stock coils at $113 each?
Or shift to Accel or similar? (At slightly higher cost and wiring hassle?)

Your input welcome.
 
Accel is good, others are, too, but this would also be a golden opportunity to ditch the points and go electronic ignition. :encouragement:

.
 
Yeah, well, ya know ...
trying to keep this project bike cheap, and I kind like the old points.
Been a long time since I had a bike with them.
And, could be handy for the EMP/zombie apocalypse ...
;)
 
I went with Dyna coils and plug wires. I also ditched the points for a Dyna S electronic ignition. I purchased them from Z-1 Enterprise (best price) all for $280 something. But even if you just get the coils and plug wires, your motorcycle will be happy👍
 
How difficult was all that?

And how much hassle was doing that?

Because, by the time I get done with new coils and plugs ... I'd be in that ballpark.
 
Another option is Boyer Bransden electronic ignition. I had it installed in my 750 before it even left the shop I bought it from years ago. I don't remember what I paid for it. I just hate dicking around with points.

I have to question your checking technique. If both coils check bad it can NOT spark on two cylinders. In any event I'd advice to keep the points as long as you can source points and condensers. After all internal combustion engines have used point for nearly 100 years. Yeah they are hard to keep in time and take a real commitment to adjust and set timing but they work.

Often these old bikes have marginal or failed/failing coils. If it were me I get new coils. They will be good for another 20 or 30 years.
