Can you do the tach seal mod for a Commando on a drill press or is a mill needed??? Where do you get the seal. I need to do it on several bikes. Thanks Mark Cigainero
I don't think he was looking for a blanking plate, rather a seal that prevents the tach drive leaking oil.Jeandr said:

Fred has a concise write-up with bore size and part numbers.

Does anyone have the standard trade dimensions for that Honda seal P/N 91207-222-000 ?
If this image is accurate,
Looks like 7 x 14.5 x 5
Can anyone confirm?

I did the seal mod 7 years ago, annointed the shaft above with moly grease a few times. It’s pushin oil now. I just thought I might have one in old machinery parts.https://www.motionindustries.com/productDetail.jsp?sku=01293548

You might want to note that there were 2 designs of tach housing and shaft. You will have difficulty assembling the type with the o-ring groove toward the top of the shaft.
Once you put a seal you might want to put a bit of oil/grease in the housing or the shaft will be running dry...
This mod was listed in the first USNOA tech digest done in the early 80's.
For the less adventurous there's this...
