I found the adjustment by ear the easier method but I also believe the primary chain makes a bit of noise. How many Miles should a primary chain last assuming proper adjustment and care.

I agree with lunatic, it should never knock. At idle a loose chain will slap around a bit, chatter not knock.
When I checked the tension in the past I would put a tape measure on the inspection port and use as much force in both directions as I could with a finger. I can remember freaking out thinking it was to tight because of the whirring noise. Not to much but a little.
Readjust it. If it keeps knocking you've got bigger issues.
Thank you.Originally Posted by Dellinger
I will give it a readjust. When I adjusted it initially I basically applied a finger touch when guaging the slack. Thank you for the feedback.
That's an important point. Just like drain plugs, I see much more damage from too tight than too loose.
Thanks, I'll try not to go full Hulk.
Does the ~1/2 inch of play have to be when force is applied both up AND down? In other words 1/4 inch of movement upwards and 1/4 inch movement downwards?
Right now I will get the 1/2 inch of play in just the up direction and then when the chain is at rest I can apply force from the top and push it some more in the down direction.

how the hell can something so incredibly simple in the world of motorcycle maintenance become so incredibly complex and difficult to perform? the complexitive and transitive nature of this very thread is going to confuse alot of board novices who are interested in tackling their own simple maintenance needs. unreal.
^^^^^word!!!
This seems the norm for all the maintenance procedures that are easily found, and just as easy to understand, in the service manual.
I feel so stupid.urrr durrr

PRIMARY CHAIN
INSPECTION
See
Figure 1-
31
. Measure primary chain tension through the
inspection cover opening. Adjust primary chains not meeting
vertical free play specifications.

See
Figure 1-
31
. Remove two fasteners with captive
washers and primary chain inspection cover with gasket
from primary cover.
2.
See
Figure 1-
32
. Check primary chain tension by meas-
uring vertical free play.
a.
Measure vertical free play through chain inspection
cover opening.
b.
Rotate engine to move primary chain to a different
position on sprockets.
c.
Measure vertical free play several times, each time
with primary chain moved so that the measurement
is taken with sprockets rotated to the tightest chain
position.
3.
The tightest measurement taken in the previous step must
be within the specifications listed in T
ab
le 1-
11
. If neces-
sary, adjust as described under 1.11 PRIMAR
Y CHAIN,
Adjustment
.
NOTE
The initial primary chain vertical free play specification used
at the assembly plant is 1/4-1/2 in. (6.4-12.7 mm) with a cold
engine. The
1/2 in.
(6.4 mm
) minimum is only allowed at the
absolute tightest point in the drive, as measured with special-
ized factory equipment. If a chain has less than 1/4 in. (6.4
mm
) vertical tension (with a cold engine), adjust tension to the
"field" specification of 3/8-1/2 in. (9.5-12.7 mm). The looser
specification will avoid overtightening, which might otherwise
occur during adjustment using "non-factory" equipment and
methods.

See
Figure 1-

. Install primary chain inspection cover
and
new
gasket to primary cover using two fasteners with
captive washers. Tighten fasteners to
