Here is the description on how to use the choke https://faq.ninja250.org/wiki/What_i..._at_startup%3F |
Well I ended up putting both bikes back to 2.5 turns out. There is little left in the riding season based on our schedules, and as much as they ran rich, at least they ran smooth and not all over the place.
In a few weeks or so I will be tearing them back apart again and inspecting the Jets, needles, enrichener movement etc. With the idle mixture screws completely closed it still ran rich and not as you are all describing it should.
I appreciate all of your help thus far, and will continue to update the thread as I progress.
Thank you again.
