I can get my bike to start with the choke pulled out. but once I put the choke back it it dies. If the choke is out as well if I hit the throttle it dies. I have replaced all the vacuum tubes, checked fuel lines, and everything I could think possible. I am getting fuel to the carb check it with a vacuum cleaner to see if air would get fuel to come out. This is a stage 3 set just kit. I took all back to stock with no change and then place the just kit back in. I have placed the needle valve in several different places with no effect. Does anyone had any suggestions or know what I am missing?
