Title: No spark
Post by: oldbiker on July 25, 2026, 02:48:14 PM

Hi all
Here I am again after a long absence. I regularly  read the posts on the forum and have had no  major breakdowns for along while. Unfortunately my r65 ls has refused to start. Thankfully it decided to misbehave at home.  I t has never given any trouble electronically so I am at a loss as to where to go next and not very proficient with electronics. I am 76 yrs now. The bike is 1983 r65 ls. I have no spark. When I switch ignition on and off I get sparks at grounded plugs. Battery is fully charged.. Where do I go from here? Many thanks and best of health to all members.

Do you have an ignition coil that is black and grey??

Sorry, I forgot to mention that I replaced coil with a Dyna coil from Rick through this forum.  My problem is to isolate the fault without too much pulling apart. In other words could it be the ECU or  Bean can?
