As far as that motor as is with out tearing it down and going nuts. (save that for when it needs a rebuild) I would start with completely new fluids, fresh clutch, new plugs, new plug caps, your new TORS kit, carb tear down and cleanup, sync carbs, check all connections and use dialectric grease, add a ground strap, gap the pick up coil correctly, compression test,(so you can moniter wear)and lastly a leak down.
Address the chassis as well. Grease everything, and if it doesn't have a Zerk, pull it apart and grease it. Adjust and lube the chain, check the axle lock nut, hub nuts, any wonky bearings, bleed the brakes, check the pads, adjust the levers and cables, check all cotter pins, check tie rods and steering components, make sure shocks are sound, be sure the radiator is clean and free of debris, grips are not loosely flopping or turning.
Once you know it runs reliable give it some bolt on goodies
