Mikuni BS 38 rebuild. (76 Kawasaki 750 twin )

[Guest]

Working on the above bike for my boss.
Has twin 38mm Mikuni BS carbs.

Will one of one of Mr. Barrs BS series o ring kits for the 32/34mm carbs work for this?
I know I won't need them all but are the o rings the same size?

Since nobody has attempted a response, I will toss in my 2 cents. I don't know that this is the right place to be asking, as BS 38 carbs are more Yamaha (650, 750 triple, etc stuff). Pretty good carbs and fairly easy to deal with. I have never seen a question quite like yours, so maybe one of the tuners on a 650 Yamaha forum, or maybe talk to Michael Morse at 650 Central.

In looking at the parts fishe it doesn't seem like those carbs share very many parts with the BS CV carbs used by the GS family of bikes. I'd take the carbs apart and see what parts you need. You can always order O-rings from an O-ring store and make your own kit if necessary.

I can only tell you that Roberts orings fit my 73 Yamaha TX 750 perfectly. Like the above mentioned, the fuel tubes are the same size as the GS tubes are.

Thank you for the replies, I just found a small baggie with some extra 32/34 o rings I had saved. I'll have a chance to test fit some various rings.
