Jets

I ordered some carb rebuild kits from Jeff at Z1 and should have in Canada in a couple of weeks. I currently have 4 pod filters on my bike, and a supertrapp exhaust. I want to go back to the original airbox, just because I live in Canada and the weather is unpredictable and I like the air filters covered in the rain. The manual says that it should have a #105 main jet, and #15 pilot jet. The previous owner did rejet the bike when he added the exhaust and supertrapp. What should I use for jets with going back to the original air box?

Thanks

Why not install a K&N filter in the orginal airbox? That way the current jetting might just be fine.

Thanks Steel. I forgot to put the make of the bike. It's a 1978 KZ1000A2.
