Hi bobby,
you mean wire-spoked wheels, eh? The artillery wheels on your bike got 7 spokes in each of them.
OK then:-
Any XS650 post '73 front wire wheel will plug straight in. '76 or earlier will need to have it's 3-part brake disk swapped for your existing disk.
Any XS650 rear wire wheel will plug straight into your hardtail frame but there ain't no rear wire wheels with disk brakes so you hafta switch to
running a rear drum.
Look at the bike photos in this list to choose which particular wire wheel option you like best and put a want ad in the list's classifieds.
&btw, amateurs can so lace up wire wheels. All it takes is time and patience. The first one takes a week, the second takes a day and subsequents take half an afternoon.
