Jetting VM26s with header & pods

Man, it's been a long time since I've here. Been hanging out on our local forum, the BC Classic Motorcycle Club ( BCCMC) an I've been through a few KZ 900/1000s. Currently have a restored Z1, KZ1000' and am resurrecting a 79 KZ1000 Ltd.

My question concerns which jets to use. The motor will be stock with stock VM26s. The air box is long gone so I'll be using pods. The header is a really cool old Yoshimura, pic attached. I have always had stock exhausts and stock air boxes on my bikes, so I have no experience with jetting.

I'm hoping someone will help me with suggested pilot and main jet sizes.

Thanks,
Ross

I have another question.

I have a choice of two sets of carbs to use. One set is from a 78 Kz1000 Ltd, the other is from a 79 kz1000 ltd. The 79 has an air screw, the 78 has a pilot screw. As well the slide/needle arrangements differ (see pic attached). The unit on the left is from the 79,the one on the right is from the 78.

I think I'll use the 78 set as it uses a pilot screw to meter fuel rather than the 79 that uses an air screw. The 78 jet needle # is 5DL31. I believe the #1 indicates the clip should be in the 1st groove from the bottom, is that so? And if I use the Yoshimura exhaust and pods, which clip groove should I use?

Thanks,
Ross
