Default No spark on front cylinder

My bike started running like **** now there is not any spark on the front cylinder. If I pull the plug away from it then there is arc tho. I tried different plugs, wires, and a new coil. Nothing helped. Any suggestions?

Why are you saying that there is no spark? If it is still arcing while pulled out from the head, you indeed still have a spark. Have you had the front injector tested to see if it's clogged or gone **** up?

There is no spark while touching the metal. If I pull it just a little bit away then it's not grounded it's just shooting an arc across the open space. As where the rest cylinder sparks hire it is supposed to, while touching metal

Other cylinder sparks when touching the head. Sorry, trying to type on this stupid phone. I just don't understand why one would get spark how it's supposed to and the other don't. But what ever is causing it is also keeping it from running note

I would suspect it's the electronic ignition. They do go bad with a little bit of age.
