Thanks but unfortunately that kit does not contain that specific jet even though the OEM refeference list shows it does. The picture does not have it shown , nor does the itemized list(it says Pilot jet but the picture actually shows the slow jet). I have not found a kit that does. For this carb the pilot jet is screwed in on top of the slow jet. i have attached my total jet count list on the picture.

I do have the one good jet for the other carb, that is what is showing in the caliper pics that I measured. Apparently 1975 was the only year to have the double jet in that tube… of course it is… the carbs that were in the bike when I got it are actually from a 1976 Honda cb360 and I was trying to restore original.A few thoughts:
1) Is there any chance someone installed non OEM carbs on your bike?
2) Did you have to drill out both jets, or do you have one good one that can be photographed?
3) It may be worth a phone call to Z1 Enterprises to see if this can be sorted out. They might go and pull the actual kit and send you a photo. Web site photos could be wrong and parts lists could be wrong.
Definitely will try that. ThanksOk, now I understand. I still think it is worth a phone call to Z1. I have found them to be very helpful.
They say brand new but not in original packaging.That's great that you got Z1 sorted on their own parts listing.
Hopefully the part you ordered from Ebay will be the correct one. Was it new or used?
from a cold start the lh header does warm up faster than the rh, however after running it for 10 mins at idle while setting the sync of the carbs I used my pyrometer and measured 297 degrees at the rh header where it enters the head, and 254 degrees on the lh one. So although the rh takes longer to heat up, it seems to get hotter. Will do this experiment again once the bike cools down. I am running the stock air box and filter. My reason for going to a smaller secondary main was the black smoke I am seeing when the bike is revving over 5000. I need to get it on the street and load up the motor before determining any next steps.If you do a cold start and let it idle for a minute or two, do both exhaust pipes get equally hot?
This is best measured with a non-contact thermometer or use gloves before the pipes get too hot.
If already answered, I apologize; are you running pods or stock airbox?
Normally if anything you need to increase jet size for mods like headers and pods. What is your thought process behind going smaller?
