CB1100 Idle speed instability problem
The Keihin JT6H throttle position sensor is available on-line.
It has been suggested that the second line of numbers (40226 on mine) may be a batch number or mold number or serial number.

A typical TPS uses 5 vdc input, outputs 0.5 vdc throttle closed and 4.5 vdc WOT. So, it is possible (likely?) that any JT6H will work, if the mounting, mating and connector is the same.

There are many sources on-line. However, my concern is manufacturing standards, as well as seeing photos showing signs of the supposedly new unit having been mounted.

Are these truly new or did they not meet OEM specs and are "seconds"?

Until one is purchased and tested, this is not a recommended source.

Just advising current research...preferably a source from Japan or affiliated with Honda...ideally from Honda direct.

Meanwhile, for anyone currently having an idle issue, please advise TPS voltage readings. A safety pin (sharp, easy to push and easy to pull out) makes a good probe into the connector middle position...or to penetrate the black/red middle wire near the connector (hole can be sealed with silicone).

1600 miles on my 2014 standard since Nov 7.
