87 XLH 1100. Have had the carb off, cleaned it, replaced the intake seals and the spacer between the carb and manifold. The bike runs fine at full throttle, but at steady speed or low acceleration it acts as if it running out of fuel. Put it on a dyno, and the afr goes off the chart lean at low throttle position. I would think it is a problem with the pilot jet circuit, but everything is clean as it can be. This carb is different from the later model carbs. It has no vacuum piston & needle. It also has a rubber plug that covers the pilot jet. Where does the pilot jet get its fuel from?
