1987 rebel 2004 sportster
My 87 cmx250 is the best rebel I’ve had. Starts instantly, runs perfectly with one exception…..it will occasionally hesitate or lose power in the high speed range. It feels like it is either starving for fuel or running on one cylinder. This only lasts a few seconds. On a hour long ride it might do this once or twice, sometimes not at all. The Chinese tank has a built-in vent and flow from the tank seems to be normal. Spark is good on both sides. Any suggestions on what i should check?
