Does a 1963 Harley Sportster have electric start if not can you put one on it?

The 1963 Harley Sportster did not come with an electric start; it was equipped with a kickstarter. While it's possible to retrofit an electric start system to a vintage Sportster, it requires significant modifications, including changes to the primary drive and possibly the frame. Aftermarket kits are available, but they can be complex and may affect the bike's authenticity.
