Frequently Asked Questions:
Why does a new carburetor not increase performance automatically?
Carburetors do not arrive pre-tuned. Optimal adjustment to the specific setup requires a jet kit with various main jet sizes.
What is the difference between the Magnum Racing and the Magnum Racing XR?
The XR designation identifies models produced from 1996 onward. The model underwent visual and technical revisions during that time, featuring 3-spoke wheels, a Paioli fork, and more rounded body panels.
Which parts from other MBK 51 models fit the Magnum Racing?
Most engine parts share compatibility across different MBK 51 models. Differences mainly involve the frame and cylinder, as certain variants are liquid-cooled.
Which spark plug?
All MBK models use spark plugs with a short M14 thread. The heat range depends on the engine: stock factory setups run fine on an NGK B6HS or comparable spark plug. Lightly tuned engines run better with a colder spark plug such as the B7HS, while full racing engines require a B8HS or B9HS.
Which 2-stroke oil is suitable?
The choice depends on the engine: stock factory setups run fine on semi-synthetic 2-stroke oil. Tuned engines require full synthetic oil, and racing engines require high-grade racing oil.
Which gear ratio provides better acceleration or higher top speed?
Improved acceleration requires a smaller front sprocket and a larger rear sprocket. Achieving a higher top speed requires a larger front sprocket and a smaller rear sprocket.
