This is just one way to make a side cover Honda cub C70 become more slim
Start from making a mold from the paper
Use a 0.8 mm galvanized plate and cut it
Important..align the plate! ... Cause I dont have a Pneumatic Planishing, I use a barbell. You also can use other tools around you with your own creativity to make it flat ...
