A larger carburetor ensures better cylinder filling and more power and torque and is almost a must for a 172ccm engine to get even more horsepower! I'll also show you how to check the reed valve block for leaks and, if necessary, how to replace your reed valve plates! Malossi also supplies a set of carbon reed valve plates with the 172ccm cylinder that can be inserted into the original reed valve block. These are more flexible and open faster when accelerating, thus improving the response of your engine! Enjoy watching!
