If you know the size order from McMaster-Carr or any other good hardware supply store.

I've probably got a couple laying around, too.  Let me know if you need one.

I thought I saw a post on here a while ago about replacing the guide pins and someone used the pins out of another bike. I think it was an Interceptor. The pins were just a little too long, so they had to cut them down.

I'll search and see if I can find that post. I'll be needing some too, for my build as I get ready to put the engine back together (Finally!!!)

Thanks KevinD, I remembered posting in that thread but had not had the time to dig it up again :)

BTW, for anyone who doesn't already know this, the second half of the part number for honda knock pins is based on the size, so for example


94301-12220 = 12x22
94301-12180 = 12x18
94301-08140 = 8x14

So, you can just 'make up' your part numbers and see if that size is available.  Getting a shorter size by one or two increments should be ok in most cases, so long as the diameter is correct.
