Hawk 250 Throttle Hesitation
Hello everyone. I just did a valve adjustment (.002 in, .004 ex) and installed a mikuni carb with 110 main jet. The bike started up great and I could hear the valves tapping slightly. The only problem is that there is a slight hesitation in the first 1/4 inch of throttle. What are the most likely causes of this? It never happened with the stock carb. FYI I live in the Houston, TX area, elevation ~100ft. I have done the airbox mod but still have stock exhaust.
Question on the valve adjustment. It was a completely cold engine. I adjusted the valves to where the desired feeler gauge had slight resistance. However, I could squeeze the next size up in the gap with a little force. Two sizes up could not fit at all. Is that ok, or are they too loose? Thanks! |
