This build is an 82' Honda CB750 DOHC which has some nice unique features, custom exhaust, axle adjuster covers.
The specs on the frame are as follows:
4" forward in a straight backbone
6" up with straight single downtube
Keep posted as it is coming apart for powder and then re-assembly,
ps: acouple of parts in the pics will be changed out at a later date, lol.
