Installed full D&D exhaust. Ordered Stg 1 Jet Kit and K&N Filter. What Pilot Jet????

Hi all,

just installed a new full D&D exhaust (header back) kit on my 01 ZX9. Now its obvious I need to rejet, but I have never done this before, so looking for guidance on what Pilot Jets I should get here.

Everything is stock so far, other than the exhaust that I just installed.

I already ordered the following on ebay:

K&N (dynojet) Stage 1 Jet Kit:

K&N Air Filter:

Now apparently the last piece to the puzzle is the proper Pilot Jet. What do I get and where do I get it? I'm in San Diego, so just about sea level. I called D&D and they literally would not recommend anything because of different locations. Can anyone please recommend what Pilot Jets to get and where to get them?

Thank you!!!

You could do like RileyDeed and install Keihin #40 pilot jets. See the thread how to fix carb stumble on 2000+ 9r's? that I just bumped for you. Riley spells out the specific jet part number on page 2.
