79mm Cylinder Piston Gasket Top End Rebuild Kit 310cc For Honda CRF 250F 2019-2025
Features:
If your cylinder blows through, the compression is too low, or even a piston seizure has occurred, then this kit is exactly the right thing for you.
Kit includes cylinder, piston, rings, pin, clips & top end gasket kit (you get exactly what is pictured).
The cylinder is made of aluminum for good cooling with an internal cast iron jacket (unlike which has a nicasil treatment).
Piston is anodized for superior heat resistance and longer lifespan.
The gaskets use performance materials to increase durability and provide greater reliability.
Includes all gaskets pictured to rebuild top end.
Kit is for big bore size - 79 mm, 17mm steel piston pin.
Compression Ratio 11 : 1.
The compression is designed for use with the original cylinder head.
When installing, ย the smaller bearing on the factory camshaft has to be removed and transferred to the new cam.
This kit is excellent as a low-cost replacement for defects in the original cylinder.

Customer Reviews
Overall, I am fairly pleased with this product.
The kit includes almost all the necessary components for a complete cylinder and piston replacement, and everything seems to be of decent quality. The cylinder itself is made of durable materials and has a good finish, while the piston appears to be well-made and fits snugly inside the cylinder.
The installation process was relatively straightforward and I was able to get everything installed and running in a reasonable amount of time. Once installed, the chainsaw ran smoothly and seemed to have improved performance compared to before the replacement.
Fast shipping,great value.
Great deal and good shipping. I will use them again.
installing was easy everything bolts right together only have couple rides on it still in break in process but after the first initial start and brake in I've been running it fairly hard and just keeps amazing me definitely would recommend and don't have rejet the card runs perfectly on stock carb with no adjustment done
Good parts, they fit just as well as the 1979 oem parts.
