| + | * Checking carburetor float level can be easily done without even removing the carburetor from the motorcycle. | ||
| + | * Simply attach a section of clear model airplane fuel line to the float bowl overflow fitting. | ||
| + | * Small diameter fuel line, which is compatible with gasoline, can be found in most hobby supply shops. | ||
