Description
It's finally done! The first ever aluminum plated center rib cylinder kit!
The cylinder is made of aluminum and the inner walls are plated for increased power and durability.
The pistons are shaped to accommodate the large exhaust ports and are designed for a good balance of weight and durability.
A special head is included for optimum performance when used with the STD crank.
[Product Features]
Extended cylinder height by 4mm.
The cylinder height has been extended by 4mm, making it easier to use with the longer stroke cranks available on the market.
Designed to allow for port timing that was previously impossible.
This kit contains all of the know-how that KN Planning has cultivated in order to achieve specifications that will satisfy all users from beginners to heavy tuners.
The combination that becomes the index is
PORT9 + STD crank + BIG carb kit (28 Φ + 4 BIG reeds + intake manifold) + G03 or G03-X.
By matching the drivetrain with the products that KN planning handles, about 14PS is acquired! The G03 or G03-X is the best choice for those who are looking for a more powerful engine.
The thickness of the outer wall of each port is also designed in consideration of the processing.
The special cylinder head uses a long reach plug type.
This makes it easy to machine the head when using a long crank.
