I do not know about the #s but I drill them out to 0.45mm This makes the bike start easier, and rev quicker.

The manual doesn't say as they are not supposed to be removed. Emissions and all that. The size is 40 though.

jetsrus.com has pressin jets available http://www.jetsrus.com/a_jet_kit_street/honda_750_CB750K_1977_1978.htm

Maybe kinda pricy but since they are hard to find, ones that work, probably worth it.

On a stock engine, with different slip on mufflers and a K&N filter, I didn't have the need to change the jet. The fuel screw is very flexible for making changes.

They should I think. I think the stock size was 40, but it could have been 35. I have it written down so I don't have to remember.
