There is a local scooter parts store here in town where I get my parts for my bike. I got rid of the original air filter because there was no way to clean it. I decided to a get a high performance air filter instead. It was not until I rode the bike last night that the filter came off. The filter was very tight when my friend installed it. The performance itself is 42mm for the 150 bikes. The one for the 50cc is 38mm. I was thinking maybe the one for the 150 is too big.
Are the 50 and 125cc agility parts the same size? I am going back today to get the smaller performance filter for my bike which is a 125 agility.
