Electric's the way to go. Oem is around 200 bucks from Honda and 6 to 8 weeks delivery or it is around here, but the Mr. Gasket 12S from O'reiley's or Autozone can be had seven days a week from any small town USA. I carry a 12S as a spare, one I ran for over a year and 10,000 plus miles with zero problems, cost new around 50.00 bucks and about 3 dollars for fittings.
