Need to clean carbies & check battery Voltage?

A bad regulator or stator.

The overriding clutch is defective, replace the starter.

My first check would be the battery to earth connection...... High resistance is a real no-no - strip, clean, re-attach to frame.

First check your voltage (12+ volts) of your battery again. If you have a 2 amp trickle charger for motorcylcles try topping off your battery on deep cycle charge over night. Usually the noise your referring to is the solenoid, more often than not this is a lack of current. Next check all of your connections on the battery and starter, that is take them loose, clean them, put them back on. Try again, if this fails, push start the bike, check your voltage at the battery while running to determine if your bike is charging. Ride the bike around for 10-15 minutes come home, shut it off, check voltage, try and start. If you have good voltage then it may very well be the solenoid, if less than 12 volts, try a different or new battery to see if you have the same issue. Hope this helps and please post the results of your "testing" so we can move forward with trouble shooting if need be.
