Description
Piston 38mm (without piston rings) 10mm piston pin - original spare part Minarelli 4T.
Yamaha is a Japanese motorcycle manufacturer known for the quality of its products.
If the cylinder no longer works properly, it is not necessary to replace the entire cylinder, in many cases it is enough to replace the piston including piston pin, piston rings and clips. For racing engines it is extremely important to keep the revision times, because the piston has very little piston clearance and is equipped with a very fine piston ring.
Technical details:
- Bore: 38 mm
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.
