So my spark is pretty weak and when I pull my plugs clean reinstall run it for a bit and check the #1 plug I can tell she works but seems like part time. While at idle I cam pull the plug wire and more Often then not (but not always) there is no change to rpm. Some times it changes and seems at high rpm it is deff firing. I'm going to replace the coils as they seem to be original. Now I've got to ask. Should I go OE or aftermarket? The bike I bought after a 907 kit was done so I wonder if I need higher primary and secondary resistance ohm. So with that thought is there a better and around the same price tag coils that I should use?
Any and all responses welcomed and appreciated
