Genuine Dellorto jet. 6mm thread for use on stock CNS 2 stroke carburetor to dial in proper fuel air mix.
You will need to learn to read your spark plug and learn a bit about tuning prior to changing jets, but it's not too difficult, and changing the jet itself is straight forward. Just drain the fuel, remove the float bowl and unscrew the jet, then reassemble.
