Frequently asked questions
Can I reuse engine gaskets?
No. Gaskets are designed to be compressed only once: reassembling them leads to oil leaks, pressure losses and premature re-opening of the engine. They are inexpensive compared to the disassembly work and are always available as a dedicated kit for each model.
When to change the timing chain?
The timing chain should be replaced when it shows elongation beyond tolerance, when it appears noisy when cold, or at the interval indicated in the maintenance manual. Change it together with the tensioner and guide shoe: the additional cost is minimal compared to the risk of breakage.
Does the crankshaft overhaul kit include everything?
In the Piaggio catalog, overhaul kits include gaskets, oil seals and bearings compatible with the complete opening of the engine. Some consumable parts (bolts, circlips) may not be included: check the product sheet for the complete list of components.
