What do you do with the choke once your motorcycle is warmed up?

• A. Turn it to OFF position.
• B. Leave it ON.
• C. Switch to PRIME.
• D. Remove the choke.

Answer: (A)

The choke is there to enrich the fuel-air mix for a cold engine, helping it start and run smoothly when it’s chilly. Once the engine has warmed up, you switch the choke to OFF to restore the normal mixture. If you leave it on after warming, the engine runs too rich, which can cause smoky exhaust, rough idle, fouled plugs, and poorer fuel economy. The “prime” setting is only for giving a quick fuel boost at start on some carbureted systems, not for use after the engine is warm. You don’t remove the choke; you simply leave it off once the bike is warmed up.
