Top Speed Bros 150 com Carburador Nibbi 28mm

Does the 28mm Nibbi carburetor really deliver more top speed than the PZ30 on a modified Bros 150? I went to the highway to test the limits of this setup and the result surprised me (and also gave me some clues about what to adjust). In this video, you will see: ✅ The real top speed test on the highway. ✅ Comparison of behavior between the 28mm Nibbi vs. the PZ30. ✅ Analysis of the jetting and performance in 5th gear. ✅ Why the bike "stuck" at 140 km/h and what I'm going to change. Many of you commented on the 18/48 gear ratio and the restriction of the airbox. In the video, I analyze whether the engine is asking for more air or if the gear ratio is too long for my weight. If you enjoy engine tuning and want to see the fine-tuning of a modified Bros 150, this video is for you! 🛠 Bros Setup: Engine: 4mm (170cc) Camshaft: [Insert model if desired] Carburetor: Nibbi Racing 28mm Racing: 18/48 Video Chapters: 0:00 - Introduction and Setup 01:30 - Heading Out for the Test 04:00 - First Top Speed ​​Attempt 06:15 - Technical Analysis: Why didn't it go over 140 km/h? 07:45 - Conclusion and Next Steps Give your guess in the comments: Ratio or Air Filter?
