CBR600 F2 Keihin Carb Needle
 

I've been rebuilding my carbs, and wanted to upgrade my slide needles, but cant find a spec for a decent performance option. I checked Keihin web page, but I cant correlate my current needles (J3WA) with anything newer that has multiple clip positions.

Since I already have jets, I wanted to get a needle similar to what factory pro and dynajet put into their kits (clip position). I've been told that these have a slightly different tapper that can be more forgiving during tuning for increasing jet sizes.

Does anyone know a Keihin needle that will fit these VP41 carbs well?
