Help missing ORIFICE, OIL CONTROL 12238-300-010
« on: January 20, 2014, 05:06:40 PM »
Hello, I seem to be missing one of the OIL CONTROL ORIFICE, If anyone has one I will be willing to pay a hefty price. A rookie mistake, I saw it there, didn't realize they came out, thought it was pressed in. If you know who has one post website.
I have 1976 CB750
Thanks, Mark

I live in Calif

Has anyone ever made one of these. I was thing to make one, aluminum or brass rod. Do you think I could get away with not having the the skinny part, just the top with a small hole drilled?

When in doubt leave it out. Probably not.

 I needed one of those for a 350f just after I joined. A member from Australia asked my address and  sent one to me. Thanks again.

Maybe someone has collected trinkets and will kick one down.

Does anyone have access to another spare one of these parts (ORIFICE, OIL CONTROL 12238-300-010)? I'm nearing the end of my engine build and could realllly use one!

I'm in Melbourne, Australia.
