Raising Seat

To place seat in raised position for access to oil tank and battery, remove seat post pin (11), lift seat up toward rear and place lower cross-shaft (9) into upper position of slot (10). The seat is in the raised position in the figure.

REMOVING AND INSTALLING SEAT ASSEMBLY (Figure 2-73)

Referring to Figure 2-73, pull out pin (1) from seat post (2). Lift seat up into raised position. Remove two bolts (3), nuts and washers which attach bracket (4) to fender through holes (5). Remove two clamps (6) which attach seat to frame cross tube (7). The seat will now be freed and can be lifted off the motorcycle.

To reinstall seat assembly, reverse the procedure given above for removal while observing for correct clearances. The seat post height should be 3 ± 1/16 in. from seat post frame to centerline of post pin hole. With upper shaft (5, Figure 2-72) in fifth or rear most slot, the seat should compress fully to its stops and the gas tank clearance must be 1-1/2 in. minimum and, there should be adequate clearance between seat and fender, luggage carrier with Tour-Pak, and saddlebags. If seat post height requires adjustment, proceed as follows. Referring to Figure 2-73, remove nut and washer (9) from bottom of seat post and remove seat post from motorcycle. Adjust rod nut (10) to obtain 1/2 in. dimension shown in figure. This dimension should give the seat the correct dimension of 3 ± 1 /16 in. Note that adjusting locknut (12) can be removed completely from the assembly and not used at all if necessary to achieve the 3 ± 1/16 in. dimension.

The 1 -5/16 in. dimension shown in the figure gives minimum compression on the seat post spring stack which, in turn, allows maximum seat suspension adjustments. The 2-1/16 in. dimension applies some preload to the seat post spring stack which reduces available deflection of springs in seat suspension assembly for heavier riders. These dimensions are determined by adjusting tension adjusting nut (13).

When reinstalling seat post in motorcycle, make sure it is adequately greased.

To establish clearance between the seat assembly and the other parts of the motorcycle, spacers may be required between bracket (4) and fender, spacer (8) in figure, and between cross tube (7) and seat base. Minor changes can be made by simply adding shim stock at these two locations.
