2 different bikes in those pics.
A pair of race bikes. No lights or indicators.
If they have HRC wiring looms, which is likely, indicators etc wont work. You will need a new "road use" loom and ignition card.
Still, pretty cheap with trick bits they have.
Scotch bright pads are great for cleaning corrosion and baked on crap off all types of metals.
Looks like #7 still has it's 2t tank, #5 looks like it might be on premix.
