    Carb Cleaning. Found Mismatching Pilot Jets

    Good afternoon all,

    91 Kat 600; someone else's old project I bought. I am cleaning my carbs, and I pulled out the pilot jets for the first time and lo and behold, one of them is not like the others!



    Larger on left, mismatching small one on right:


    This bike has a full V&H exhaust system, stock air filter and a jet kit; the needles have the adjustable perch thingies. So I'm guessing the genius before me lost one of the pilot jets and figured "Hm, i'll just substitute one of a different size." This could help explain the poor running when I bought it.

    I am doing this bike on a budget, and would really prefer not to buy an entire aftermarket jet kit just to replace one missing jet. Is it possible to order a replacement set of just pilot jets, or somehow figure out the size and replace just the one?

    Thank you all! This site is endlessly helpful.

    The lone one on the end is what they should look like. Jet kits don't include those. Buy 4 new jets, they are cheap. 32.5 is the size.....I think, check the manual for the size. Yup, 32.5 is the size. http://katriders.com/wiki/index.php?...Specifications

      The size is 32.5, none of those pilot jets are the right one. The stock pilot jets don't have any bleed holes in the body.

          Thanks for the help guys - interesting. I know carb tuning and jet selection is a deep rabbit hole - but would it be prudent to get slightly larger-than-stock sizes given the exhaust?

            Not the pilot jets. If all you have is a slip-on, you most likely don't need larger main either. You'd need to check the tune once running.
