Hi dwayne,
psychobilly is right, i used to own a cg 125 (an old model anyway) and suffered the same problem regarding revs in 4th gear. It was due to a combination of a bit of water in the carbs plus a worn out battery. try draining the carbs first and if it still persists then try a different battery.
As far as the clutch goes clanking is never good take the right side panel off the crank casing and have a look at the clutch plates (which should be visible) and check for damage and discolouration.
hope this helps you to find speed again,
Nige.
