Aftermarket exhaust? High flow air filters? Looking for more power? You're gonna need to up-jet. Or maybe you're just cleaning the carbs and need some new stock size jets? We have the entire range available from #35 - #45. slow / pilot / idle jet. These are aftermarket jets made in Taiwan, they are quality reproductions.
Make sure to look up the stock size in your owners manual and start there. Honda changed the carbs on the 550 and the 750 in ''77 so make sure you have the older threaded style pilot jet.

Outer diameter: 5.5mm
