Mikuni BS34 vacuum slide spring needed was created by atownbrg
Was cleaning the carbs this weekend and noticed that one of the springs that go under the vacuum caps on top is longer than the other 3. Not sure how it got stretched out..
My bike is a 1983 GPz 750 A1. Mikuni BS34.
Anyone have one and can help me out?
Thanks

My carb springs were different lengths in the original BS34's, so I carefully stretched the others to match the longest one, and everything worked just fine.
In fact, the carbs seemed to work even better than before.
