This image is of my 1980 KZ-250 with its head removed. In this
picture you can see the timing chain retained with a yellow zip
tie. This prevents the timing chain from falling into the
crankcase and maintains tension on the timing chain preventing it from
losing position on the crankshaft pulley. They head was sent to a
local machine shop for a valve replacement. This maintenance was
completed successfully allowing me to maintain mobility during my
college career.
