Bought kits for my PD 41 on my 77 CB750k from vintage cb750.com. The jet needle that came in the kit has the number Y41 stamped on it. The needles removed from the carbs are stamped F2D51E .I assume they are original as this the needle that the shop manual specs. Although they appear to be the same length their is less taper on the point of needle. Don't know if overall taper is the same or not. Any info on this is appreciated. I can't find any specs on the web for of these needles ant can't find anyone who sells the originals. Will the Y41 work? Help!
