Is there a particular order in which one should completely disassemble a 750 4?
Drain and remove the gas tank, the side covers, the battery, and the seat and place them in a safe location.
Drain the oil from the engine and the oil tank.
After that if it were me I'd start by removing the back wheel and work my way forward from there.
Remember to take lots of photos to help you remember where things go...... It really helps.
