Removing Pilot Jet, HOW?

I am cleaning the carbs after a 3 month sit, the bike runs very rough.

The service manual stated I should remove and clean the Pilot Jet.

How is this done? Special tool?

There is a small "flat" on the side of the round brass base, and no place to insert a screw driver!

CA model only?

Thanks in advance, I did a search, no luck.

thats the air fuel mixture screw not the pilot jet. the pilot & main jets are accessible once you remove the float bowls.

you could try just running some carb cleaner though first.. Say SeaFoam or Yamaha carb cleaner.. (I have heard good things about both)

MIXTURE SCREW removal then...

OK... Thanks, It was difficult to tell from the photo, I am sorry I called it the wrong jet.

I Have the Pilot and main clean now...

HOW do I remove the MIXTURE SCREW for cleaning??? Do I need to, now that the others are clean?

(The service Manual calls this mixture screw: "the "pilot jet" since it cautions: Turn it all the way in gently, count the turns be fore removing for cleaning) And the seat will be ruined if you turn it in tightly. I agree this sounds like mixture, but the manual calls it Pilot?

I am using carb cleaner in a spray can. New Plugs.

i takes a special D tool to remove. the tool comes with the factory pro jet kit & is available from motion pro / honda / web etc.

it's easier with the carbs out to just use thin needle nose pliers to back it out & then use a dremel to put a slot in it ( for a flat blade screwdriver ).

you can then use the common 90 degree a/f mixture adjustment tool ( $20 )

Fixed, Bike runs great!!!

Thanks Tim.

I left "it" in and sprayed carb cleaner in the small hole in the carb throat, and the solvent came out of the 3 small holes next to the butterfly, so long story, I left that part in.

The good news: Bike runs great!!!!!

Must have been some scale or whatever happens when you don't ride often enough in the jets, and "brakecleen" did not do the job on the first carb clean.

Thanks for the help everyone.

Carb spray is stronger than Brakecleen. Barryman's B12 Chemtool is best in my opinion. Don't use either on soft plastic parts.
