pilot jets kz650

Im piecing together a 77 kz650.Im putting a 4 to 1 exhuast and individual air pods.I looked up the jetting on a link through KZrider and it said to go up 3 sizes on mains to 110.It also recomended i move up 1 size in pilot jets.Here inlies the problem:One set of carbs has pilot jets marked 15.The second set of carbs I have the pilot jets are marked 50.
1.Which jets do I go by?
2.Where do i get bigger pilot jets?
The frame is painted and ready for engine and everything else to be installed.These are the only parts needed to get it going!
Thanx Guys

The #110 recommendation was based on a baseline of #102.5 main jet stock. Your #50 "pilot" VM24s don't have #102.5 mains stock... they are much smaller; probably #90.5 or something like that. I doubt using a #110 main will hurt anything so give it a try regardless of what mains you find in there or a #105 main; either will work.

Your pilot jets are #15 on both sets. The one with the #50 barrel jets OVER the top of the pilot jets was made a bit later and they used the extra set of jets to restrict gas flow to the pilot jets. Either set will do well with #17.5 pilot jets. Unscrew the #50 jets and put them in a safe place... they don't need to go back in. Unscrew the #15 pilots and replace with #17.5. They are MIKUNI VM22/210 type and you can get them from www.z1enterprises.com
