JD Jetting Keihin PWK Carb Slide
JD Jetting Keihin PWK Carb Slide, Keihin PWK carburetor slides with higher or lower cutaways are used to adjust the closed throttle to 3/8 throttle range jetting.
Installing a higher number slide is leaner at low throttle positions and can help fine-tune your jetting beyond the usual effects of needle clip position, pilot jet, and air screw adjustments.
A lower slide number will richen low speed jetting to help reduce detonation, or allow running the motor in colder conditions with improved response; a leaner carburetor slide change extends the useful jetting range for riding at higher elevations too!
Note: Yamaha YZ250 owners must also purchase the Cable Holder (P/N JDKH16) for this slide.
