Frequently Asked Questions:
What does “LC” mean on a Peugeot 103 SPX?
“LC” stands for “Liquid Cooled.” This distinction matters because the LC versions have a completely different cylinder and a cooling system with a radiator, coolant hoses, etc.
Which carburetor fits the Peugeot 103 SPX?
The stock carburetor is a 14 mm Gurtner. However, a Dellorto SHA carburetor is easy to fit and easier to tune for modified setups.
Which drive belt is suitable?
A drive belt for the RCX or SPX is required, regardless of the cooling type. Various brands offer standard and reinforced versions. Reinforced drive belts are recommended for tuned engines.
Which spark plug is suitable?
These engines use spark plugs with a short-reach M14 thread. However, the heat range depends on the engine: an NGK B6HS or an equivalent spark plug is sufficient for a stock engine. A colder spark plug such as the B7HS is suitable for a mildly tuned engine. A racing engine may use a B8HS or even a B9HS.
Which two-stroke oil is suitable?
This depends on the engine: a stock engine only needs semi-synthetic two-stroke oil. A tuned engine requires fully synthetic oil. A racing engine needs high-quality racing oil.
How much two-stroke oil should be mixed with the gasoline?
The oil content in the gasoline should be 2 to 3%. For a racing cylinder, following the cylinder manufacturer's specifications is recommended.
Does the stock cooling system use thermosiphon circulation or a water pump?
The stock cooling system uses thermosiphon circulation. However, manufacturers such as Polini offer retrofit systems with a water pump for tuned engines.
