Hello, I have now finished uncorking my bike, jetting, carb. boot, airbox, and drilled out the pipe. Unfortunatly it still will not run unless the choke is ON at least half way. Jetting is: 170 main, 68s pilot, 53 needle at 3rd position. Im at near sea level and I have adjusted the pilot screw to the highest rpm. and then readjusted the idle to 1400rpm It runs great, but something must still be wrong. Any help would be apprceiated.
