My 1972 Honda Z50.
Before, a pretty good candidate all in all.
After, I obviously opted for a restomod instead of a straight restoration.
Some of the mods include and 88cc big bore kit with race head, 20 mm carb, performance exhaust and oil cooler and manual clutch conversion. Bigger (280 mm) rear shocks, +1" chromoly front forks and HD springs, Heidenau 4 X 8 street tires front and rear. Those are some of the bullet points, obviously more went into it so if you have any questions about the rest of the bike let me know.
