KZ650 converted to electronic fault

Hi guys good news she seems fine now all 4 cylinders running nicely and pulls throughout the range ?, bit baffled but least I know the 1016 and the ignitor are all good. Cannot explain the weird choke behaviour as mentioned for the last couple of years I have owned her its taken up to 10 minutes before I could ride her without choke as she would just bog down on throttle ?, today the highest rev's on full choke was only about 1500 ? but I'm not bothered as she ran fine and I could ride her within a couple of minutes of starting from cold ?
Anyway thanks for all the input and data, I'm sure this topic will help others.
