Posted by Anonymous on
Hi, Anonymous and the usual suspects are:
1. Fuel boiling in fuel line due to extremely high outside temperatures and unprotected fuel lines missing convoluted tubing cover routed too close to cylinders and or heads.
2. The gas cap is not venting properly.
3. Fuel tank vent line blocked, plugged, kinked, or smashed.

Bigger jetting (a higher fuel/air ratio) will not cause overheating. But an air leak between the engine and carburetor can cause overheating - and an erratic idle. Make sure the carb is correctly connected and there are no air leaks. An air leak could also be the cause of the popping that you were attempting to address by re-jetting.
Once any air leaks are corrected, adjust the idle mixture screw to attain the highest idle speed when the engine is at normal operating temperature. Then, use the idle speed screw to set the correct idle speed.
Finally, ride the bike at full throttle for a short time, pull the clutch and coast to a stop. Remove the spark plug and check the color; a tan or light brown color indicates correct jetting. Too light = too lean. Too dark = too rich.
