Disassembled 4 Times & Still Broken? Deep Overhaul on a BMW S1000RR Engine!

Throwback to a video I shot 3 years ago! A big brother from Zhejiang brought us his BMW S1000RR with a nightmare issue. The engine had already been torn down and reassembled 3 or 4 times by other shops, but every time they revved it, the engine timing completely jumped, almost smashing the valves. He was completely stressed out and left it in our hands for a definitive fix. Watch us pull an all-nighter to strip it down, uncover hidden red flags (shonky sealant, burnt parts, and loose chains), deeply clean every single component, and rebuild this beast the right way! ⏱️ Video Timeline 00:00 The Zhejiang brother’s BMW S1000RR is back: Unfixing a broken engine. 00:20 Midnight teardown: Investigating the chronic timing jump issue. 01:34 "100% Factory Original"?
