I'm naively trying to create a post that will be part resource for those needing to properly jet the K4 or relative for 4-into-1 and/or stacks. Before my head is ripped off, I'm not pushing for pods although success stories (no dead-zones, tuning nightmares, etc.) with pods + 4-1 are welcome. There's so much confusion out there, myself absolutely included. Apparently, the '74 was factory-rich because of some lawsuit, adding to the confusion. I cannot find any "right" answers and I understand there probably aren't any. But those with success jetting these superbikes are encouraged to help me and other newbies get it right without too much carb benchin'. Thank you all in advance!
I just found a '74 with no-mods and under 4k miles! She's going the direction of the cafe, however I'm keeping the original seat, chopping rear fender, adding drag bars, and 4-into-1 exhaust for her pre-summer mods. Although I've been entertaining the idea of running pods, I've decided to keep the stacks-in-a-box airbox and going with 4-into-1 exhaust. Got a cracked header joint. Essentially, I'd really like to know what to re-jet my mains to for 4-1 with exhaust, airbox, low altitude. For the distant future, I'd also love to know configs for 4-1 + stacks if I dare in this dirty-ass city.

K4 or relative questions:
4-1 + airbox
Mains?
Pilate turns out?
Needle clip positions?
4-1 + stacks
Mains?
Pilate turns out?
Needle clip positions?
4-1 + pods
Mains?
Pilate turns out?
Needle clip positions?
Other configurations too, like open headers, anti-pods, high altitude, etc as it's all great to know. And if any config requires bigger slows.
Thanks!
