i hate not getting at least one reply to my post. so here is one for yours. In 84 there was a big thing about japanize bikes being too powerfull. so the guv passed an import law. the bike makers tuned them down and droped the 50 of there bikes 650-600, 750-700,ect. i am remimbering this from something in the news the facts might not be exact. a 83 manual for the 750 should cover most of the stuff on your bike. but then again i do not have one so i could be wrong here also. but still i at leaste am making a guess. good luck ...God bless....Mack
