DR 250 jetting

Discussion in 'Technical and Troubleshooting Torque' started by Gpz lover, Dec 2, 2009.

  1. Have a DR 250 with staintune exhaust. has a problem with fuelling up and creating a flatspot round 3rd gear midrevrange, sometimes popping off after. has a baffle in , believe to be original jets. just wondering if any one has had exposure before i go rip tear bust into the pig of a thing.

  2. Should be a pretty easy task to set up a single carby properly.
    - Clean and service
    - Set Float Level
    - Main jet (about $7 each)
    - Needle height (if no clips then use thin washers to raise it)
    - Idle jet and screw (poor idle screw settings can be felt when cracking the throttle at any speed)

    In that order
