I have a 1996 F3 with the California emissions. The PO had purchased the bike from LA with a Vance and Hines slip on and he added a K&N filter. Once I got it to Colorado it was running extremely richblack smoke above 8K RPM and and little to no power from 5K-6.5K RPM. I started with plugs, cleaned the filter, sync'd the carbs.After syncing it spit flames on decleration, but otherwise ran much better but still lacked lower range power so i took a go at adjusting the pilot jets, now it runs smooth from 3k-redline but seems to flood the cylinders if it idles for more than ten seconds which sucks at lights to rev it to 4k just to go without bogging. . . So now I have pulled the carbs to clean them and re-adjust. looks like the first owner had installed a jet kit. My manual says that all my main jets should be #135, I have a #140 jet on 1,4, and #142.5 jet on 2,3 and 40S jet for my pilot jets, along with an adjustable needle. The 142.5 say "RD" on them and the #140 jets, along with the pilot jets have a symbol that resembles a star or a k (see my rough picture below) I'm trying to figure out if anyone knows who makes this kit so i can find a starting place for adjustment.Or do I maybe need smaller jets? I operate my bike normally at 5,000 ft elevation but regularly make runs to 6,500 ft.

Here is what I have so far... Any help would be greatly appreciated.

Sorry for the book I just wrote, new to the F3, and motorcycle carbs.
