Description

The intake funnel replaces the original air filter.
An increase in power is primarily achieved by the strongly overprivileged flow of the air correction nozzles. This causes the mixture to lean more as the engine speed increases than with the standard air filter (the standard air filter partially covers the nozzle block (main nozzle block and idle nozzle block) and thus ensures a linear function of the air correction).

Air jet correction
With an intake funnel, the air correction should therefore be selected fatter compared to the setup with original air filter. As an example: air correction nozzle main nozzle stock series: #160 should be reduced to #140. Likewise, the secondary nozzle, which is designed in two parts with a fixed integrated air correction nozzle, should be selected fatter. Here, too, the air correction portion is decisive, not the size of the gasoline passage hole. Thus, with the auxiliary nozzle, 55/160 becomes 55/140 or 55/120.

Correction of the gasoline proportion
If the air correction proportion is not changed, the gasoline side of the nozzle sticks must be heavily greased. This means that the main nozzle must be enlarged disproportionately to compensate for the increased lean of the air correction. As a rule, however, this leads to a very heavily greased mid-range, which makes it impossible to run the engine cleanly at partial load.
