!
Thank you for purchasing a Yasuni exhaust.
For the proper operation of your exhaust, please follow the instructions in this manual in detail.
If you have any questions about mounting and/or using your exhaust, please contact your nearest Yasuni distributor or
visit our official website: http://www.yasuni.com
CAUTION
Check that the motorcycle is in a safe position to prevent it from tipping over and causing any kind of damage.
Make sure that the parts you have received are those that appear in the list of parts required to install the exhaust.
The silencer is a product that can reach very high temperatures, so it should not be placed near parts of the vehicle that
are not heat-resistant, such as fuel pipes, brake pipes, plastics, etc.
Once the exhaust pipe has been installed, do not stand behind the silencer when you start up the motorcycle for the first
time.
MOUNTING
1- Remove the original silencer and manifold if necessary.
2- If Yasuni does not provide the manifold curve, slightly loosen the screws that join the original manifold curve to the
cylinder.
3- Join the silencer with the cone manifold, aligning the spring hooks (without attaching them)*.
4- Mount the silencer support and, if necessary, mount the bracket to the frame.
5- Position the silencer and leave it with loose screws, meaning that you can easily put it in its place.
6- Once in position, tighten all screws including those that join the silencer to the frame of the motorcycle.
7- Also tighten the screws of the plate to the cylinder.
8- Finally, tighten the screw of the flange that holds the cone manifold to the curve.
9-Start up the motorcycle and check that there is no gas leakage.
Any modification or alteration of the approved exhaust silencer is prohibited, in which case Yasunimotor S.L. waives any li-
ability concerning or related to the use of material that has lost the benefits of the standardisation. In addition, Yasunimotor
S.L. waives any liability arising from defects and malfunction of the altered or modified product. It is highly recommended
to use a qualified technician for the assembly and operation of exhaust systems for motorcycles, as Yasuni is not liable for
any damages caused by an improper assembly of the exhaust. It is necessary to carry out an inspection of the hooks after
100 km of use. To obtain optimal performance, you should check the carburetion of your vehicle according to its state of
repair and conditions. It is normal that, after installing the silencer, it will emit white fumes. This phenomenon may occur
for the first 100 km after installation.
* The spring clips of the silencer and the cone manifold may not be completely aligned
MAINTENANCE
Regularly inspect the silencer supports and all the elements which may suffer from wear and tear due to use. A possible
change of the colour of the silencer is normal, as this phenomenon is caused by the high temperatures that the product
reaches. Proper maintenance involves the use of specific products, so cleaners containing acidic additives should not
be used.
NON-CONTRACTUAL DOCUMENT.
Yasunimotor S.L. reserves the right to make all necessary modifications without prior notice in order to improve the quality
of its products.
