41.-CHAIN
The secondary transmission (chain, sprockets, guide, etc.) supports your motor-
cycle hard work. It is also one of the most important assemblies for your SAFETY.
It requires constant maintenance and obviously, correct.
Chain tension
1. Motorcycle without load and the sidestand posi ti on: It must be a space of
35 ~ 60 mm between the chain and the swingarm at the rear of the guide.
With the fi ngers and without excessive force, you can check it.
2. Loosen the axle nut (1).
3. Find the point of maximum tension of the chain.
4. Through the nuts (2) of the swingarm, match, through the notches in the
swingarm and the lugs on the adjusters, the alignment of the chain at both
sides of the swingarm.
5. Tighten the nuts (2).
6. Tighten the nut (1).
7. Check back at the point of maximum tension and readjust if necessary.
The chain tension is a constant check. You must check the state of the string
itself, the guide, the front and rear sprockets too.
Usually, when a chain is too used, stretched more than 2%, should be replaced.
Usually it is the right ti me to change, guide, front and rear sprockets. It is for
prac ti cal reasons, economic and security. A chain in the limit of its life has par ti ally
worn teeth rear sprocket, guide, etc. If you mount a new chain and other compo-
nents are not changed, its life will be shortened by 40% and already deteriorated
elements like the front and rear sprocket will end their life quickly. In the medium
and long term the most economic is to change the complete transmission kit at
each chain change. Your GAS GAS o ffi cial service will provide it.
Lubrica ti on: The chain is the type with o-rings, this requires a special lubricant,
use the same lubricant in the guide and the chain guide shoe, front and rear sproc-
kets.
NOTE: We recommend you always have the chain properly lubricated, those
chains that are dried, lubricated, le ft to dry, and so on., Shorten its life and the life
of the components that surrounds it a major way.
