Description
Piston Naraku 75cc for Kymco, SYM standing.
Naraku produces tuning and racing parts for scooters and maxiscooters; although their focus was initially on the widely used GY6 engines, the brand now offers tuning and spare parts for all types of two-wheelers.
The piston with piston ring(s), piston pin and circlips is the moving heart of the cylinder. Due to the constant up and down movement, the piston is subject to wear. At some point the tolerances are no longer correct, the piston ring no longer seals perfectly and the performance decreases, i.e. the piston must be replaced.
When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
