GSX-R 750 Pictures of how I cleaned and adjusted the carburetors on my 1985 1986 1987 Suzuki GSX-R750 motorcycle.


But first, lets pay some bills:

  1. I open up the float bowl, and here is what is inside. OK, now I need some graphs and charts with circles and arrows. Stay with me.
    1. Pilot Screw
    2. Starter Jet
    3. Pilot Jet
    4. Main Jet
    5. Needle Jet
    6. Float
    7. Float Needle
    8. Float Pivot
    Carburetor parts


  2. View of an exploded carburetor. Exploded view of a carburetor. What all do we have here. Left to right:
    1. Needle Valve
    2. Retaining Screw
    3. Floats
    4. Float Needle
    5. Pilot Screw O Ring
    6. Pilot Screw Washer
    7. Pilot Screw Spring
    8. Pilot Screw
    9. Pilot Jet
    10. Main Jet Washer
    11. Main Jet
    12. Float Bowl
    13. Float Bowl Gasket
    14. Float Bowl Drain Screw



  3. Here is the carburetor top cap off, revealing the diaphragm. The diaphragm is connected to the slide, held down by the spring, and there is a jet needle down there under the spring. Oops, didn't get a shot of the Pilot air jet. Sorry. It's under the diaphragm. I swear.

  4. The Jet needle, with the spacers and clips and whatnot, in the right order. Thick washer, e-clip, metal washer, spring seat. I have the metal washer and spring seat on an ice pick for instllation.

  5. To install the jet needle, I dropped the jet needle, with thick washer and e-clip attached, into the center of the diaphragm. Then I put the spring onto the ice pick and held it back. Then I put the metal washer and spring seat onto the ice pick, and carefully loaded the washer and seat onto the top of the jet needle, then slowly released the spring to hold them in place. So easy a highly skilled neurosurgeon could do it.

  6. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!


  7. Then I finished my beer.
