花1280元复活沉睡30年的本田CBR423｜废铁重生 战斗风机车复活记

I spent ¥1280 at a scrapyard in the northern suburbs and brought home what looked like a pile of junk — an old Honda CBR423 from the 1980s. At first, I thought it only needed some cosmetic work, but once I opened the engine, I found a true mechanical nightmare: cracked block, seized bearings, and a destroyed crankshaft. This was my first full engine rebuild, from measuring cylinder pressure, welding the block, replacing the crankshaft, syncing all four cylinders, to fabricating a custom engine stand, sandblaster, and aluminum casing restoration tools. After hundreds of hours, I transformed that pile of scrap into a battle-style beast with a raw metallic matte finish. A journey of sweat, oil, and pure passion. 💪 🛠️ Chapters: 00:00 Buying a scrap bike for ¥1280 01:00 Discovering severe engine damage 03:00 Full disassembly and rebuild 06:00 Cylinder sync and first engine start 08:00 Custom frame and battle-style build 10:00 Matte metal painting & final assembly
