How do you convert a razor dirt bike into a gas dirt bike?

To convert a Razor dirt bike into a gas dirt bike, you'll need to replace the electric motor with a small gas engine, typically a 49cc to 110cc two-stroke or four-stroke engine. This involves removing the existing electric components, modifying the frame for engine mounting, and ensuring proper fuel and exhaust systems are installed. Additionally, you'll need to upgrade the bike's brakes and suspension to handle the increased speed and weight. It's crucial to check local regulations regarding modifications and safety standards before proceeding.
