MZ TS 250/1 || Krümmer kürzen || Testfahrt

Between 5,000 and 6,000 rpm, the engine revs like a stick of chewing gum. It's a different kind of lively. To optimize this, I'm shortening the manifold by 4 cm. I hope this will improve the resonance at higher rpm, but also hope it won't have a negative impact at lower rpm.
