1983 KZ650-H3
Last out was the KZ650CSR -H3 in 1983: The big updates here was the same engine covers as the Z650F4. And much unlike Kawasaki CSR models, the H3 had forged wheels. Actually the H3 had a lot of minor updates like modified battery/tool case, slightly updated CW carbs. Minor update to cylinder head and head cover. It got new pistons with four rings. Different in frame fittings and updated forks internal and externals, air valves at top of fork. Mid year 1983, generator details changed. Small change to starter engine.
Together with the F4, this was the last KZ or Z650.
