#48 pilot jet on a 1200?
I've been messing around trying to get my fuel mix right after installing a Ness big sucker AC, it already had drag pipes on it.
Right now I have a 46 pilot jet in,which is what CV Performance recommends for my bike. But after doing some plug chop tests the plugs are still very white. I've checked several times for air leaks that might lean out the mix but haven't found any. I've also checked some of the other carb/jet threads(there is a butt load of them) and it seems most bike that aren't running stock are using45/46 pilots.
I'm thinking I'll order a 48 pilot and see how it goes-I'd rather be too rich vs. too lean. Just looking to get some thoughts from some more experienced folks and see what you think.

The pilot jet was the one that gave me trouble, so I distinctly remember I had to go to a #48 on that one. If memory serves me (it was 6 years ago), I took the main jet to 180 (maybe it was 185). I should have documented it all but didn't. I'm running an S&S Teardrop AC with Screaming Eagle II slip-ons (the "old" originals that they no longer sell) with Thunder Monster baffles.

Yep, nothing wrong running a #48 if needed.

48 jet
190 main
1.5 on the idle
1250 10.5:1 ,.030 squish, stage 2 Buell lightning heads, N4 cams, CV carb, dyna 200 Iggy sf set-up, stock 2;2 exhaust with se slip-ons. ++
If the bikes breathing it will need fuel, if the bikes running well, it has what it needs. Plus don't mix needle/jet kits, stay with one brand.
