Replacing the Belt on a Piaggio Si

Model: Piaggio Si
Part:

Video tutorial

As usual, before starting the maintenance operation, place the scooter in a stable and secure position to work on it. After removing the mudguard protection (located near the pedals on the left side of the scooter), proceed to remove the actual belt.

Unscrew the variator bolt using the appropriate spanner, and remove the pieces one by one until you reach the fixed pin. At this point, replace the old belt with the new one and reassemble the variator and other accessory parts.

To secure the variator properly, tighten the bolt with the spanner while simultaneously blocking its rotation using a screwdriver (as shown in the images).

How to replace the exhaust on a BMW S 1000 RR?

To replace the exhaust on a BMW S 1000 RR, loosen the bolts that secure the silencer to its housing, located on the right side of the vehicle near the mudguard. Once the mounting bolts are loosened and the clamp connecting the exhaust to the collector has been widened, you can remove the old exhaust. The new one can then be inserted into its place, allowing you to secure it to the corresponding mounts and subsequently connect it to the collector; at this point, check that everything is functioning correctly.
