Nach 6 Teilen endlich gelöst – DAS war der Fehler an meiner Optima! 🥳🔧✊️
In the 6th and final part of my Hercules Optima tuning series, I finally find the real problem that's been haunting me: ➡️ A bent cylinder stud! In the video, I spot the defect right in front of the camera and fix it. Afterward, the Optima finally runs like it should with the NTS cylinder 🔥 For comparison, I then reinstall the Athena cylinder – but the engine runs just as poorly as before… So it's clear: The Athena was apparently also part of the problem. Thanks to everyone who followed the entire series and tried to solve the mystery along with me 🙌 Let me know in the comments if you would have guessed the cylinder stud was the culprit! #HerculesOptima #MopedTuning #AthenaCylinder #NTSCylinder #TwoStroke #Troubleshooting #DIYProject
