Jet needle adjustment
(For EUROPE)
On the carburetors used in the YZ125, the main
nozzle is a non disassembly type, so it can not
be replaced. Therefore, carburetor setting
requires the change of the jet needle.
1. The jet needle setting parts, having the same
taper angle, are available in different straight
portion diameters and in different taper start-
ing positions.

Changing from 6CHY6-82 to 6CHY5-82 has
the same effect as a lowering of 0.5 clip
position.
