Re: Greetings,need help with new motorbike
Welcome to the forum. Check for a stuck throttle cable. Make sure the slide in the carb comes all the way down (remove the air cleaner to see that). If that checks out, it could be an air leak on the intake side. Put "air leak" into the site search window and see how others solved it.
