76 KZ900 jetting suggestions: stock air box, 4 into 2 exhaust

bike has been set up for pods and 4 into 2. p.o. switched it back to stock airbox and filter, running rich. anyone have a good starting point for pilot and main jets, for my 76 KZ900 with this setup?

#115 mains, 5DL31-3 jet needle clip, #17.5 pilot jets. If it is still "rich" the problem isn't jetting. See our web site and look under "wg's Tech Stuff Index" and read the "valve clearances" and "coil repowering" tips.

thanks for the info George.i'll give that those settings a try.
