125-200cc CR/WR 165 jetting specs for sea Level

I purchased my nephew a 2012 Cr125 with a 165 kit. Wondering what jetting works best for the stock carburetor at sea level. Seller told me it was jetted for a 144. He also included a Lectron carb with the bike. I always heard the Lectron carb was more suited for riding at higher altitude.
Any thoughts on what the jetting should be?
Any carb baseline settings would be appreciated.
I did look at the 125 jetting pages but did not really see what I was looking for.
Thanks

Is it the stock Mikuni? I don't have specs for that for your area. I always felt like I was chasing my tail with the Mikuni because it was pretty finicky. I would probably want to get the Suzuki needle but will need to see if I can find the right one for you. Then a 470 or 480 main and a 25 pilot. This is just spit balling as I haven't jetted for low elevation and high humidity.

Thanks for the help. Bike has stock Mikuni. Seller said it was jetted for 144 kit. I always thought a Lectron was for higher altitudes. I am at sea level normal northeast weather (seasons). I will check the Lectron I have this weekend and see what it has, I am not familiar with them at all. Could use some help setting up that carb. I was surprised the owner took off the Lectron and went back to stock carb.
