worb5 vespa engine case

The machinings on the engine block are actually divided into two areas: the inlet (at housing inlet) and the overflow ducts.
Here are usually still hidden PS. Especially with Vespa and Lambrettamotoren it is useful the overcurrent channels... MORE

A well-running engine also includes optimized compression. Because you should neither risk an overheating or even a hole in the piston, let alone renounce performance. It is important that the compression ratio... MORE

worb5 vespa steel sliding bushing

Aluminum cylinders can be provided with a casting bush. The advantage is that larger pistons can now be driven. This leads in part to a drastic extension of the lift. It is preferable to use... MORE

worb5 vespa clutch
worb5 vespa clutch

Tuned motors require a stronger clutch which is capable of transmitting larger torques. This is achieved by increasing the friction surface (4 instead of 3 washers) or / and by increasing the contact force (reinforced springs). Often the coupling cage must also be used... MORE

In the case of tuned engines it is indispensable to set the ignition precisely. If the ignition is too late (less than 15 degrees), a lower power yield can be expected. If the ignition is too early (more than 25 degrees) is usually a hole in the... MORE
