Sherco Carb Jetting
Instructions
This manual provides instructions on how to remove and reinstall the
stock carburetor, it also shows you how to change the pilot jet and
the main jet. It is intended to be used for all Sherco 1.25 – 2.9 Trials
Motorcycles.
The motorcycle shown is a new 2002, 2.9, the one that you are
working on may be slightly different but the principles shown will
apply to all of the models indicated.
The technician shown in the photographs is David Chaves who
received his training at the Sherco factory in Spain. David is also a
member of Team Sherco and is competing in the NATC national
series as a Champ rider.
The stock jets are: Pilot 30 – 33, Main 124 – 126.
Sherco USA recommends a 36 pilot and a 118 main for most North
American applications. Altitude, temperature and atmospheric
conditions all have an effect on carburetion. Your local dealer should
be able to advise you as to the best jetting for your area.
The float height should be set at 18.5mm.
If you have any question or are not certain about any procedure call
