New RS38's, what main jet to start?

Got it together tonight and went for a ride, carbs are so out of sync, sounds like its cammed to the moon
Lots of jump, seeing about 12-13 A/F at cruise but 14-15 when I give it throttle so tomorrow I'm going to raise the needles 2 notches and sync it.
I didn't want to wind it out because of the lean a/f.
And YAY, looks like all my oil leaks are fixed, although I won't know for sure until tomorrow.

Me, or the bike? LOL
Some yoyo PO mixed up the #2 and #3 bowls. The #2 has the passages for the A/P.

You have to be one to ride it.

Your bike is going to be a madman

Installed the carbs today, runs ok for not being synced yet, one float leaked and the A/P wasnt working so I have the bowls soaking in carb cleaner. Some blockage in the A/P bowl passages. Hopefully get them reinstalled and synced tomorrow.

I have a 1327...track 160, street with baffle is 155...

Ok, I guess I am putting the 152's back in.
What size pilot jets do you run?

In your 1300+ cc engine?
Mikuni jet size of 145-155 would be a good starting point I would think.
Hopped-up 1100's (1168's, etc.) typically use 142.5's and up.

Of course, after no one else answered your question and I did, now the rest of the crew will correct me.

What size of main jet should I start with for my RS38's? I put in 140's, they had 152.5's when I got them, I dont know what kind of bike they were used on.
