Fit a 19mm carburetor and the expansion chamber (keeping the stock 50cc cylinder). Dyno result: 5.8 HP, smooth torque curve, safe EGT. Swap only the stock exhaust for a resonant expansion chamber
Drag a 70cc cylinder kit onto the engine. Do not change exhaust or carb. Dyno result: 5.0 HP, but the torque curve is narrow (peaky). The EGT warning light flashes red—risk of overheating. Have you tried the demo
