And that a strange issue, Blank issue. I would say do nothing and right that bike into the ground.

Pull out the reeds and have a look. Make sure the petals are clean, not bent, or cracked.

If they check out, look into the flywheel. Make sure it's not cracked and the woodruff key is still there.

Flywheel key is probably sheered or even a almost fouled plug check it first!
