This is a super cheap way to improve the reliability and reduce the maintenance required on your vintage bike. This filter slides over the top of your in-flow pipe of the petcock. This will stop dirt, rust and other particles from getting into your carburetor and gunking it up. This is a must do when you remove the petcock for maintenance.
It will only fit a pipe that is 5.44mm in diameter. Check your petcock pipe before buying.
To save you money, this item will ship by stamped envelope with extra postage for thickness.
