where to get new slides for the bs 34mm mikuni????

Here are some pictures of the first shots of the BS34 Diaphragms.

Another picture. Because there is no key from rubber to slide there is no key on the lip of the rubber. Everyone who is smart enough to be able to change the rubber will be smart enough to know how to index the slide in the carb body. I will have pricing in a couple of days on them, but it will be most likely $125 for the four rubbers plus post. These will work on all Mikuni BS34 KZ700/750/1000/1100 carbs.

Thanks for keeping us posted Otto. I picked up a set of BS34's...just to have. Glad to know you may have diaphragm replacements.

Just found out from the molder that he is sending me three sets this week. These are production test shots and will be of production quality. If anyone requires some. I still don't have a definite price though just the estimated minimum price he gave me. So the $125 is the price for now until he raises my price.

In the wise words of sponge bob "Its the best day ever!"

:laugh: So ready be shure to let me know how those work out I have about a month or two of riding left but I will have the $$$ for ya shortly after sturgis!!

Hope my kz does good up there round all them HDs

:silly:

Production "rubbers" are ready. I am very happy with the new material we are using and the quality of the product itself. They are a little softer than OE Mikuni and just as soft as OE Keihin rubbers. This should produce a bit faster response and no binding, such as can be experienced with older rubbers. All that has to be done to use these is to cut off the old rubbers and the retaining rings and slip on the new rubber. They can be glued on if you wish but I dont think it will be necessary.

Otto...what might you be wanting for a set of four?

somethin like 130 + shiping not bad and you can do it all your self .
I plan on using a set and will post my results

I now only have three sets left. Just so you guys know.

these diaphragms can be bought off ebay for $19 a piece, don't know where oktar is justifying making $50 on a set of 4,guess being "middleman" pays off ($130 + shipping) lmao

Go and buy some of those. They are made out of the same material as what the boots are made out of that go from the carbs to a OE airbox, and they are 80 shore A hardness. Mine are made out of Nitrile rubber and are shore 55 hardness. Once you install them you will find the difference real quick. Also you are aware how hard those boots get once they get exposed to heat a few times and to Gasoline. I bought those rubbers and tried them. It took a total of over 15oz Yes almost 1lb, to compress them. It takes 1.7oz to compress mine. Now imagine how they will react in a carburetor wit only vacuum moving them and being under spring load. You are not showing me something that I do not already know and have not already tried.
As you can see on this picture with the other guys diaphragm at the bottom. There is a Nology ignition coil, a KZ1000 cam cap with bearings and a small flash light (not visible) stacked on top of this rubber. The scale is showing 12oz and the diaphragm is still holding. These will work fine in a constant speed Rotax engine for ultralight aircraft when you slowly throttle up and hold constant throttle. They however will not respond to the usual "cracked" throttle on a bike.
