Whats the best carburetor for my bike?
Again, this will depend upon your engine setup and riding conditions. In general, we recommend using the smaller carb when two sizes are recommended and in no case would we use a carb that is larger than the intake port. The larger the carburetor venturi, the harder it will be to tune, especially at lower speeds. A 26mm carburetor can support over 20hp and most of the 110/120cc engines on the market come with 18mm or 20mm carbs from the manufacturer. Install a carburetor that’s too big for the motor and you’ll spend all of your time trying to make in run right below redline; by the time you get that straightened out, it’ll run rich at peak power. Forget that expensive 28mm precision fuel leak for your 88cc bore-up motor and save yourself a lot of headaches. Flatslide carbs are difficult to tune and tend to have on/off throttle response, thus are best left for racing machines.
