Just started my 77 cb750a after setting the carbs and adjusting the idle to what seems a vary low setting.
When i select 1st gear it will try to move if i don't hold the brake is the normal for this bike.
I haven't changed the oil yet could thin oil be the problem?
 
When you put it in gear does the rpm increase? The automatics have a vacuum motor that bumps idle speed up when put into gear to keep it from stalling. You may need to adjust the idle up to a lower rpm.
