My bike runs okay at moderate speeds, and it seems to have a nice sweet spot around 4K. However, slower riding is hard work with some surging and a general lack of smoothness. I assume it is the carb, the exhaust also smells rich. I think the pump nozzle needle may be missing. I'm using the 100 main. The secondary throttle valve is being opened by the throttle cable rather than the diaphragm, maybe that's what is causing it, but with the diaphragm only - the secondary throttle valve would not open. Any ideas?
