Jetting your quad can be
a tricky thing. With
this guide, and
subsequent list of users
jetting specs we hope to
take much of the guess
work out of this task.
If you are not familiar
with jetting a
carburetor or would just
like to know how your
carb works and what jets
affect what area of the
throttle then I suggest
checking out our full
blown Jetting Article. |
