BS34 Orings?

buzzstpoint · May 9, 2014

So I need to replace all the orings in the carb and need to find a good source.
I think I may have found one.

I have a 81 xs400 Special II
BS34 carbs.

I came across:
http://www.cycleorings.com/#BS_Series_O-ring_Kit

When I emailed him, he couldn't confirm that the rings would find our carbs.
Are all BS34s the same?
Has anyone used these kits?

Looks like they will work. A good way to look for o-rings for the 80-82 xs400 carbs is to look at stuff for the 80-84 xs650 stuff. They are the same and a lot more available.

I'll admit, I don't know much about '81s, but I just got done going through the carbs from my '79. I know the '81s have O-rings on the idle mixture adjustment screws and there are throttle shaft seals (which are not O-rings, but I guess the right ones may work)...but there are no O-rings in my carbs. Other than the idle mixture screws, where do you use O-rings?

I don't see any quad o rings in that kit for the butterfly shafts. As I just did mine a few days ago, here's what you'll need:

The butterfly shaft use a seal not an o-ring. Hough the 80-82 carbs have a o-ring for there float valve seat and are pressed in to the carb body. Unlike the earlier ones that screw in.
