Recently my TVS Apache RTR (2008 version) engine started overheating. While driving within 2-3 km the engine starts heating very badly and the idling RPM goes above 3. While once the engine is cooled then the idling RPM comes back to normal slowly. Is it some problem with carburetor?

Being a new rider i have very less experience with bikes. Please help me?

It could be the carburetor, or the tube that connects it to the engine, or even the petcock.

Most modern carbs have synthetic rubber diaphragms that can tear, allowing excess air through. If you have a vacuum-operated petcock, the tube that connects it to the carb could be going bad, or the diaphragm in the petcock could fail.

Assuming you have done no carb work recently, it is unlikely that the carb has come unseated from the induction tube, but the tube could have cracked, or the seal between it and the head failed, possibly because the bolts/nuts that hold it on have loosened.

Being air cooled, the fuel mixture is the most common suspect, most likely from a vacuum leak of some sort.

You did check the oil level, correct?
