I have never heard a motorized bike engine (tiny Chinese 2 stroke) so not sure what it should sound like. I have had many motorcycles including some single cylinder 2 strokes. The top end on this seems knochy to me, maybe that's normal for these. There's a low whiring sound when the clutch is engaged and I'm moving that I couldn't capture. Does anything sound obviously bad or out of ordinary? The engine is a Zeda 100 Firestorm, only has about 5 miles on it. I know I need to tweak the carb adjustments and check for any vacuum leaks.
