What I am looking for are the stock return springs for the needle slide assembly. These are the four large springs that go under the top vaccum caps. The bike is a 1990 CBR1000F, non-Cali model. Thanks for your attention.

Most guys on the forum will have complete spare sets and won't break them.
I have a full set of carbs if you want to go that route..............
