I just got a used 2000 mojave last week. Ran flawless first couple days, took it trail riding later and it would choke, cut out and even die. So I took it home changed plugs that helped, now when I let off the gas and hit it again it coughs then takes off. Could the carb be set to rich, to lean, jettings wrong? Its a great machine and it makes me mad that it's doing this. Any help would be great.
