I recently fitted a new top motor mount and this meant I had to remove my coils and coil mounting bracket. I also had to have a tank mounting bracket welded to the frame. When I put everything back together and tried to start the bike it would only fire on 1 cylinder. I removed the ht lead from the rear cylinder to see what one was not firing and as it still ran on one cylinder it had to be the rear cylinder not firing. When I held the plug cap near the spark plug, it started firing on both cylinders but when I put the cap onto the plug it stopped firing again. It does this all the time now. Does anyone have any idea what could cause this to happen. I’ve tried different plugs and swapped the front and back leads around. I’m really baffled by this.
