  MACHINE TUNING As shown below, each of the asterisk (*) marked parts is located between the air/fuel passage and has its own air/fuel mixture adjustable range in terms of the throttle valve opening. The chart indicates that the car- buretor can supply correct air/fuel mixture to the engine in any range because of the overlapping adjustable range of the each part.

  MACHINE TUNING MAIN SYSTEM MAIN JET (M.J.) The main jet, like the slow jet, meters fuel flow. Each jet size is indicated by a number. Larger number means a larger bore diameter and fitting a larger number main jet enriches the air/fuel mixture.

• Page 71
  MACHINE TUNING Jet needle clip position To adjust the air/fuel mixture with the jet needle, change position of the needle clip which is set in the 5th groove. The lower Lean groove the clip is moved to, the higher the jet needle rises and the larger the clearance with the main nozzle becomes, resulting in a richer air/fuel mixture ratio.

  MACHINE TUNING CARBURETOR TUNING IN PRACTICE In the previous section, basic principles of carburetor tuning have been discussed. Described in this section are the bases for carburetor tuning required when coping with variations in air (oxygen) concentration. VARIATION IN AIR (OXYGEN) CONCENTRATION AND CARBURETOR CONDITIONS As the air, affected by the temperature, altitude and humidity, gets expanded or compressed, air (oxygen) concentration varies accordingly.

  MACHINE TUNING 4-21 SUSPENSION BALANCE Balancing the front to rear suspension properly is the most critical adjustment for suspension performance. If the front forks are adjusted harder than the rear suspension, such as changing to heavier front fork oil, stiffer compression and rebound setting, air pressure build up in the forks and so on, the front forks will collapse less on bumps.
