The carburetors and carburetor kits we deliver have to fulfill basic quality requirements in order to guarantee problem free installation Individual fine tuning for each motor is up to every tuner to carry out. For optimal motor output, we recommend using both a larger manifold and racing air filter. Further, larger valves ensure higher power performance. In any case, reed flaps should be exchanged.
The bottom of the line - a larger carburetor means a noticeable increase in rpm‘s, which means more power and higher top speeds.
