The carburetor has been specifically designed for emissions control operation. All jets are fixed at the factory.

Carburetor controls include throttle, enrichener and idle speed adjusting screw. Operation should be checked and adjusted at proper intervals. Refer to Maintenance Scheduling → Regular Service Intervals: Softail Models → Regular Service Intervals: 2006 Softail Models.

NOTICE

Operation at higher altitudes (approximately 4000 ft. (1200 meters) elevation) can require carburetor modifications for best engine performance. See a Harley-Davidson dealer for these adjustments. Failure to do so could result in equipment damage. (00206a)
