Hello, I am new to this page and I was hoping to find some answers to my issue. I have an issue where my 1981 cb750k will idle fine (900-1,100 rpm) when first started. If I use the throttle and bring the rpms up they tend to stay around 2-3k which is quite high. The weird thing is that i can thread out the main idle knob and the rpms will come back down. It seems like it is threading itself in when I use the throttle and is preventing the throttle plates from returning to a low enough position. All ideas are welcome and appreciated. Thank you guys!
