Frequently Asked Questions
1. Is a battery required for this motor to run?
No. Thanks to Yamaha's Battery-less EFI, the engine creates its own electrical current for the fuel injection system through the manual pull. This makes it perfect for lightweight setups that don't need a heavy battery.
2. Can I add electric start to this model later?
While conversion kits exist, they are mechanically complex and costly. If electric start is a requirement, it is highly recommended to purchase the F20SWHB or F20SWB models which come factory-equipped.
