    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.

Tired coils and bad wires

I got caught in a rainstorm this week. My caps, wires or coils are bad.
Rather than dicking with 30 year old parts I thought I would go with Dyna coils and wires.

I know we have 3 ohm coils on the bikes but what is the difference between the mini coils and the green coils. DO any of the variants of the min and the green coils work identically to the OEM format of a wasted spark system?

Ignition will not be changed due to a total lack of options in that area.
 
I have a set of the Dyna coils(green) on my Yamaha Seca 750, TCI and they are fine.

I was warned by a Dyna Coil distributor to stay away from the mini coils for a street bike. They are a weight saving product for drag bikes and do not perform well in a high duty cycle situation.

I second Chucks advice. It's fairly easy to replace the wires on the stock coils. If you leave the wires a few inches too long you can re use them on the new coils if the stock coils turn out to be bad. Then your only out an hour's labor.

Replace your caps first then run tests. They do go bad with age and moisture. Same thing happened to my bike in the beginning. The wires can be replaced, but you would have a lot hotter spark with a set of Dyna green coils and Dyna suppression wires.

Coils don't really go bad, it's extremely rare. 99% of the time, it's the wires and caps. Even my vintage guy won't sell coils, because he says they don't go bad, haha. I tried to get one for my 750, and I had to convince him the previous owner put the Wrong coil(3ohm coil) on my bike, and it was eating up my points.
 
Try a used set of Bandit coils for 39.00 on ebay. After you check/replace wires/caps. Todays coils, cheap price.
