CJR Performance Adjustable Air & Idle Screw

This allows for an on the fly idle adjustment without the need for tools. Works with both Keihin and KOSO throttle body. Great for riders that want an easy idle adjustment or to increase idle slightly to improve low RPM throttle response. Adjust your smaller idle screw first, then use the brass air screw in 1/8th-1/4th turns to further refine the idle RPM.  CJR Performance Adjustable Brass Air Screw - 100% Brass design to allow the most precise CNC machining- Double O-Ring design for added support of the weight of the extended shaft- Requires using the OEM air screw spring- Knurled handle finish for easy grip- Optional short and long version availableCJR Performance Adjustable Idle Thumb Screw- Knurled thumb screw to allow easy idle adjustment- Included spring to ensure tension on the threadsCJR Air/Idle Screw Combo (Both)- Includes one (long style) brass air screw and one adjustable idle screwNOTE: In 2014 the KOSO 34mm throttle body came with this brass air screw.
