VintageCb750 has alot of parts. Sometimes they are out of stock,though. The jets for these carbs fit several other bikes that used these same carbs. You dealer should be able to get your jets no problem. I have 3 size 40 piolt jets if that is what you need.
I feel guilty that you broke a jet. I'm the jerk that told you to do it that way
They are soooo fragile
