When re-assembling, if the web strapping running from the top back of the seat frame
to the middle cross bar of the frame is removed, it must be re-installed at the correct
length. Note that this strap is used to support the seat metal plate from resting directly
on the fuel tank. The front seat straps are not adjustable but the rear ones are.
Consequently, the strap must be adjusted to the correct length at the upper end to avoid
sitting directly on the fuel tank.
