How to Replace the Spark Plugs on a Triumph Street Twin

Model: Triumph Street Twin
Part: Spark plugs

Video tutorial

Follow these steps to remove and replace the spark plugs on the Triumph Street Twin motorcycle. First, place the motorcycle on its centre stand and start by disconnecting the spark plug connector; then use a socket spanner to unscrew and remove the spark plug from the cylinder head, as shown in the video.

At this point, install the new spark plug of the correct type and with the same thread pitch; screw it in by hand and then tighten gently with the spanner to the correct torque, applying the same procedure for replacing the other spark plug in the engine!

Vespa Immobiliser: How to Transfer the Chip from the Old Key

In the case shown in the video, the new keys are not recognised by the ECU: the Vespa starts but does not run (thus the immobiliser is active). The solution shown in the video involves locating the immobiliser chip in the old key (the one recognised by the ECU). Open the cover on the key (only red master keys or some blue ones), remove the chip (which is a small black cylinder or rectangle), insert it into the new key in place of the new one, and try to start. Now the key will work. If the master key is red, it will definitely work. If it is blue, it might work: you need to cut the silicone; this is possible but a delicate operation. If it is a black clone key, then it is a system that does not work.
