Yamaha SR250 Air/Fuel Screw Kit - JADUS

Free shipping for orders over 90 euros in Spain

This air/fuel screw kit is developed to make idle and off-idle fuelling adjustments easy.  Adjustments can be made by hand, on the bike, on the fly - to adjust for seasonal air density changes and temperature changes throughout the year.  Make your bike run like a dream the whole year round with simple finger adjustments!

The design is a direct replacement for the Yamaha SR250 stock screw. The screw will work just like stock but may be around half a turn to a full turn more or less different from stock (due to machining tolerances). But because they are so easy to adjust, this is no issue at all!

The screws are machined from solid brass to precision, with tolerances held to within +/-0.05mm.  The heads are polished for a slick look and the four cut out details make dialing in and counting turns a breeze.
