In that box... do you have any ignition switches, fuel caps, seat locks, helmet that have lost their keys or have broken parts, cut wires, snapped keys etc etc?
If so, then rather than store them forever I would love to take them off your hands and welcome all dead and dying keyed items as Ive worked through my stash of lock parts now.
Im also happy to take those random loose Yamaha keys that dont fit anything if you have some lying around as well.
(of course, these dont need to be LC or RZ or even Yamaha, most of the Japanese manufacturers bought lock/ignitions from the same suppliers back in the day, Ive happily culled parts from random Suzukis as well
)
