This guide provides technical specifications, maintenance procedures, and tuning steps for the Mikuni BDS26.
The Mikuni BDS26 is a 26mm downdraft, constant velocity (CV) carburetor commonly found on multi-cylinder motorcycles like the Yamaha Seca II and the Hyosung GV250. Unlike standard slide carburetors, the BDS26 uses a vacuum-operated diaphragm to control the throttle slide, ensuring smoother throttle response and better fuel atomization across various RPM ranges.
For optimal performance, clean the carburetor every 12,000 to 15,000 miles. Fuel System | ATKUSA
