Does anyone know how to raise the needle jet on a Keihin CV Carb. I looked online a few places and all I can really find is definitions on what it does "1/4-3/4 throttle." It's for my 75 XS 500.
</blockquote>Anyways last time I checked my needle doesn't have notch and I was able to find something about using shims or washers. Even then I am not really sure where they are placed and how it's done.
Anyone have experience with raising a needle jet on a Keihin Carb? Maybe some images?
1/4 TO 3/4 Throttle <blockquote> The JET NEEDLE is the most effective component in the range. Changing the STRAIGHT DIAMETER (D) will change the calibration in the transition range from the SLOW circuit to the MAIN circuit (1/8 to 1/4) throttle. A smaller diameter will make this range richer and a larger diameter will lean this range. TAPER (A) changes are only made if there is a problem balancing the calibration between 1/4 and 3/4 throttle. If the mixture is rich at 1/4 throttle and lean at 3/4 throttle, a JET NEEDLE with a larger taper is needed. If mixture is lean at 1/4 throttle and rich at 3/4 throttle, change to smaller taper. If the calibration is lean from 1/4 to 3/4 throttle, raise the JET NEEDLE by lowering clip position, or use JET NEEDLE with shorter length (L1). If the calibration is rich, lower the JET NEEDLE with a longer (L1).
