Removing stock carburetor and cables.
Figure 1,
1. Remove seat, front fenders and gas tank.
Make sure fuel petcock is in “ON” or
“RES” position. If it is in the “PRI”
position it will allow fuel through it.
2. Remove throttle cable, (and housing if
installing a twist kit) from throttle housing.
Pay close attention to routing when
removing cable as the new cables will need
too be routed the same.
3. Disconnect choke cable from stock
carburetor before disconnecting it from
handle bar and remove.
4. Remove stock carburetor.
5. Stuff a dry, clean rag into the intake
manifold to keep debris from entering
engine.
6. Remove stock rear head stay from frame
and head.
7. Remove plastic vent box from right side of
frame along with hoses.
NOTE: The vacuum line can be left off if the
engine is run while the petcock is left in the
PRI position. This may want too be
considered by racers who do not depend on a
reserve. If you choose to do this, the black
vinyl cap must be left on the carburetor vacuum
fitting and the spare cap can be placed over
the vacuum port of the petcock.
