Stiffened and mildly modified the frame, all bearings (including swingarm) upgraded, new cruisetech tires, forks upgraded with performance springs and front lowered 2.5" (the 77-78 bikes have longer forks than the earlier models), longer rear shocks to keep stock ride height and stretched the rear 2".
Relaced and completely rebuilt the rear wheel to go with a 160 tire. Still kept the factory diameters on both tires. Added the inner fender and finished the tail light.
