KLAPPENAUSPUFF & MAPPING an HARLEY DAVIDSON ILLEGAL?

Legality of valve exhaust systems, mapping, and camshaft tuning on Harley-Davidson motorcycles. In this video, I discuss the legality of valve exhaust systems (e.g., Jekill & Hyde), ECU mapping, camshaft tuning, stage kits, and other modifications using my Harley-Davidson Low Rider S117 as an example and my experience working at a dealership. Learn what's permitted, what rules apply in Germany and Europe, and how these modifications can affect your operating license, insurance coverage, and potential suspension during a police check.
