STEERING BEARING RACES/CARBURETOR CAP
fl: Steering bearing races (Fig. No. 18-1)
Both inner races (referred to as RACE #2 in
Parts Book) have been modified to provide
greater strength. Originally, top and bottom
inner races were id~ntical, but are now two
differently sized races. There is no change,
however, in bearing balls,
These parts have been included in standard
models after engine #26308, and should be
used as replacement parts on all JT1 1 s.
NOTE: The front fork guide (Fig. No. 17-27,
JTl Parts Book) cannot be used with these
newer bearing races because the inner race
holes are now too small to let the guide
pass through, This part is not absolutely
needed as its only purpose is to help align
the underbracket during installation.

J2: Carburetor cap (Fig. No. 2-20)
The carburetor cap design has been changed
to permit an elastic steel band to be in-
stalled around its outer edge. This will
help to hold the cap more securely in place.
These parts are standard equipment on JT1
1
s
after engine number 025908.
New and old caps are available, but the new
cap can be interchanged on earlier machines
without modification.
