Topic: Stock Jets

[750Man]

I recently took my carbs apart to clean them and noticed that the main jet was a size 105. I am wondering what the stock jet sizes are for a 1975 CB750 K5 because I think the previous owner may have changed them. I will be buying new jets from servicehonda.com soon and want to make sure I get the right ones for a stock bike.
Thanks

If your carbs are the originals that came with the bike, (carb nos. 086A or 657B)  they do indeed come with 105 mains according to the info I got from a post a long time ago. My k5 has them.

I just checked and they are 657Bs, so I guess the 105 main jets were right. Thanks for the info.
