Restoration of a 82 Z1000j1

z1000j you say,south africa, you say,wider swingarm,welcome,we can and will help.
check out roynor's(kzrider member) project thread.he is installing a suzuki tl 1000 swingarm on his z1000j.there are several swingarms that can be modified to work and as has already been suggested the search function should reveal lots of info.
z1109rfin has a thread on his bike and he installed a zrx 1100/1200 swingarm.
i took the raod less traveled and custom built my own swingaram out of 4130 cro-mo,to accept a 2000 r1 rear wheel and tire and brake system.i too kept the dual shocks.
hth,here is my bike.
