I bought a set of 37.5 size 'genuine Keihin' idle jets from them, and the are neither marked "K" nor are they marked "37.5", but are just stamped with a "38". At their prices, and with their no-return policy, this doesn't appear to be right: the last time I bought these they were marked properly and with the stylized "K" as well.

If they were a Keyster jet, they would look just like these...   >:(

I ordered some jets a year or so ago from them.
I got the proper size K marked jets.
If you ordered 37.5 and they're stamped 38 sounds like they sent the wrong jets and should take them back.
Do you have a copy of the Honda Shop Manual or Parts List for your bike? Get one here:

I tried to order Keihin 37.5 a couple years ago and they said no go.  I don't think that particular size exists anymore.  Give them a call and ask what's up.  They are very knowledgeable.

I purchased some main jets from them for the 550 a few months ago, they were not marked with "K" either, but they had the right number on them (100).

I ordered them by the size, and they matched exactly to what I had.

Hopefully they have not fallen to the "new management" system and have become a take it or leave it company

I ordered some for my 550 as well. They were identical to the ones I took out as far as fit. Don't remember if there was a K on it or not.

When they came to me they were in a plastic bag, not a Honda bag.
If the weather holds this weekend I'm going to try them out in my 750: the years of MTBE ate enough away from my idle jets that I've had to run with the air screws at the end of their active range, leaving little room for adjustment with the wildly varying fuel we get in Colorado.
