High quality big bore cylinder kit from Polini.The Polini big bore kit is one of the highest quality kits on the market today. The increase in displacement and compressiom gives the Yamaha what it needs to perform. A 44mm light alloy bore with great wear resistance due to the Nickel silicon coating is the starting block. Stroke matching and thermic expansion is reduced with the die cast piston using the new Omega design. Compression is then increased with a Polinified piston dome and fine chrome faced piston rings. Each kit is also supplied with an up rated pressure regulator calibrated to the Polini kit and original exhaust which allows for a generous fuel delivery without the need for additional gear cases.
