Hi Tomy, doing a restoration, want it in original condition. Found a manual on Ebay from the States, get shortly! Yep started pulling apart on weekend, thinking the wiring is going to be the fun bit! First time doing something like this, so a challenge. Cool on the 76 J1...
Thanks Monkey
Hey mate, here are some workshop manuals you can download. There is none for the l1979-1982 z50jz like yours but mechanically they're the same as earlier soft tails 1974-1978 z50j1 (known as the k3 to k6). Main differfences are the body styling (tank/seat/side cover/tailight/headlight) and wiring/switch block so it should get you out of trouble.
also if you look at the exploded parts diagrams found on cmsnl then you can often work out how things work, its also good for getting part numbers to order parts from your local honda dealer.
