🚲 Bike Engine Carburetor: Optimized Performance for 2 Stroke Bicycle Motorized Engines (80cc, 66cc, 60cc, 50cc, 49cc) Review

The carburetor is fine but I can't fully retract the cable. The carb then runs like a vacuum leak, and I know better because I'm a licensed motorcycle mechanic.

Here you play Russian Roulette. You can either get a quick carb or a fake crappy carb. I was lucky and got a high speed carburetor. Others received Chinese NT. I've been looking for fast carbs for a very long time and finally found them.

Not quite the same as the pictures, the part I was looking to buy said speed on the carburetor side, I have one with Chinese characters on the side and inners Share and Receive Features are different than what I was planning to buy, but it's still a good carb.

I just installed a new high speed carburetor, it works fantastic, my bike put in a few miles per hour and for the price I've just ordered 2 more for my other 2 IAM bikes. In one of the reviews I read, the person said it's a cheap Chinese carb, but if you look very closely from the side, the carb says speed, but it looks the same as the NT carb , but the speed carb works better than the carbs.

This is a great 80cc carburetor when tuned. You need to know how these carbs are balanced in order to achieve great performance. I had to increase the throttle cut to make it run lean between 1/8 and 1/4 throttle, it took some experimentation. You need to know what main jet is recommended for your engine and body size and set the needle jet to just under 4 cycles. Compared to the NT carburetor, it has a larger throttle body, an improved needle and poppet valve that won't overflow if you forget…
