Have a 76 CB750K I’m turning into a cafe/Bratt style. Frame has been cut and hoop welded. Gonna run the standard 19” front wheel with 18” rear wheel. I’m totally new to the motorcycle world and am wondering what length shocks would be a good starting point? I know the factories were shot. But I also know with the factory length there is hardly gonna be any clearance between the rear tire and the sub frame. Just wondering what length everyone else has used. Thanks in advance.
