Topic: CB750 DOHC Comstar wheels ?

[Jonabonospen]

I have a 1979 CB750KZ DOHC and have some questions on wheels.

Firstly my bike has got Comstar ( I believe ) wheels on and has twin front disc brakes and rear drum brake. I then got some wheels off a guy and he advertised them as off a 1980 CB750 but when the wheels arrived they are different. The rear wheel has a disc brake on it so will not fit my current setup, and then both wheels are like reverse comstars (best I can describe them) as the metal plates they are made of seem to be facing the opposite ways to mine.

Can someone tell me what models had drum and what had disc rear brakes? What had twin front disc brakes? And which had Comstar wheels and which had reverse Comstar wheels?

Cant say about the 750 but the 650 had the reverse comstars  in 79 and on the customs untill 81 and on the 82 nitehawk.  All rear drum and the 79 was 17" but the rest are 16".    The 81 custom and 82 nitehawk had dual disks on front.
