Chain Adjustment, Go/NoGo

Hey all, saw another chain adjustment thread on the first page but didn't want to hijack it.

My bike is missing the "New/Replace-Chain" sticker on the swing arm. Can someone take some measurements off of theirs from the end of the metal of the swing arm to the marks and post them?

well i wouldnt take much notice of a sticker anyway..
even those lines are only a guide..

best regularly clean and lube your chain
then align it carefully, including sighting along its
top run [from behind rear sprocket, like aiming a rifle]
checking for any lateral movement, or bowing,
out of straight which indicates sprocket/wheel
are out of alignment, thus forcing chain to run
unevenly, with side pressure on sprockets..

start with the stamped marks tho as a guide
beginning with the sprocket side, then
taking the brake side back to the same mark..

you want an inch or more slack measured
at lower chain run mid way between swingarm
pivot and end of swingarm [approximately]..

reason for changing out both sprockets and chain
is mainly so that worn sprockets, dont damage
the new chain..
stock sprockets will last well with good
chain maintenance/adjustment habits..

if that indicator for chain replacement
was critical it would be marked so
with those indicator lines,
not with a sticker..

if in doubt or for peace of mind etc,
take a ruler into your dealer
next time you visit..

If you can answer the questions asked in response #6 , we can give you a pretty good answer about your chain wear.

Personally, I've found that folks tend to run their chains too tight.

The lift from the rear sprocket is done parallel to the axle bolt, in the center of the chain's wrap around the sprocket.

"This is also a good time to check the chain for wear. Regardless of adjustment, pull one of the chain links off the rear sprocket. If the chain lifts off the sprocket more than half the height of a tooth of the sprocket, the chain is worn out. Replace it right away and you won't have to replace the sprockets as well. Sprockets must be replaced when the teeth show signs of hooking, or a difference in profile between the back and front of the tooth. Never put a new chain on a hooked sprocket."
