Ignition fault

Hi has any one out there can help me with an ignition fault. I’ve got no spark at plug checked points are opening ,checked the coil is earthed,made sure there’s no earth to the coil when key is switched on ,don’t know what else to do can anybody help ?

Hi I've had the same trouble, but I found an old plug from my car and it sparked fine, I'd just replaced the plug, so I'm wondering if the NGK plugs that everyone seems to use are either faulty or more likely copies, I've ordered a denso one see if that works

Tried 3 plugs 😡 no joy

Hi well my denso plug came I put it in bike started ran great switched it off, won't start, no spark, I wonder do these bikes burn spark plugs out if something is wrong
