K8 its a 78 ....
K7 its a 77
ect....

F models have a thinner tank and dual disks upfront and a rear disk..

77-78's are unique....

longer trailing arm...
different carbs..
630 chain (as oposed to a 530)
17in rear wheel..
good looking lines...
better tank lid (kind of locks sorta)
crome head light ears..
different caliper.. (front)
different master cycl (front)
various updates to the motor (to many to list)

i guess 77-78 motors are kinda like 75 "F" motors they are really good and supposedly the best of the years to modify they have better combustion chambers and better flow in the heads and they have accell pump carbs so if they are tuned right there is NO flat spots i know mine ROCKS!
