My chopper's left spark plug always wet, hence start up got some problem. Does anyone know what cause this (is it because I using the side stand)? Any solution?
wat bike r u riding?
twin carbs? maybe u nid to sync your carbs or the float in your carbs r not in good condition anymore so excess fuel gets in your carbs wen u park as the fuel flow doesnt get cut off.
senario 2 is highly unlikely but worth a check.
Another possibility is piston/piston ring worn out. Engine oil seep into the combustion chamber and causes wet spark plug. Just check your spark plug, if it is oily then my assumption should be correct.
