Why is your cr 125 bogging out when you take off?

Your CR 125 may be bogging out when you take off due to a few common issues. It could be a result of an improper fuel-to-air mixture, often caused by a dirty air filter or a clogged jet in the carburetor. Additionally, check for spark plug issues, such as fouling or incorrect gap, and ensure that your clutch is functioning properly. Finally, if the bike hasn't been maintained recently, consider examining the overall fuel system and ignition components.
