vin problem....

hey everyone, im redoing a kz1000 for a friend and he has really hacked the wiring in the front trying to rewire a new key switch, i have the bike all repainted and everything so now its time to tackle the wiring issue. i have looked in the filebase for a scematic but cannot seem to find anything that matches the vin numbers that i have on the bike. he says its an 81, but theres nothing that matches in 80, 81, or 82 on the filebase. here are my vin numbers....

Frame-- ukakzck1 ba001065

engine-- kztooje001631

if anyone could help that would be awesome thank you in advance!

First letter of the frame number should be a 'J' not a 'u' then it all falls into place as a 1981 KZ1000-K1 model AKA LTD

well thank you very much! i was kinda starting to wonder about that since none of them started with a U, but figured id just be safe and ask anyways lol.
