Last month the back cylinder on my 03 750 began to starve for gas. I removed the carbs and found a clogged idle tube. I put everything back together and both cylinders run fine once it warms up. That brings me to a new problem; warm up takes forever even on a warm day. When everything was right I could give the engine partial choke and start riding. Now all it does is starve for gas with the slightest throttle action until the temperature goes to fully warm. Then the only other running issue is an occasional flat spot between 2500 and 3000 rpm while accellerating. The bike has been marbled, the idle adjustment plugs removed, and it has vance and hine pipes. Is there something wrong with the choke? It is connected and seems to be moving correctly. What else could have gone wrong with the carb job? I need help, I want to ride, but my bike won't let me! Thanks.
