The GSXR throttle bodies do not mount directly to DCOE manifolds. The spacing is different (easily fixed with the individual bodies) and as you have
noticed DCOE's mount with a bolted flage. You would need to fabricate a suitable matching flange with a short length of tube which can be
joined to the throttle bodies with a short length of silicon tube and hose clamps.

Hi friends
I am new to this board, and I got here because of this topic. I have a Miata engine which I am considering buying a Weber/Mikuni manifold for,
because I read that the GSXR's mount right to the DCOE manifold, but I see that the Webers are flange mount (as is the manifold.) The gsxr
throttle bodies appear to be cylindrical on both ends, so how is it that they basically just bolt on to a DCOE manifold.
I appreciate any and all responses.

The TBs attach to flanges bolted to the GSXR head via rubber mounts. The 750 flanges can be unbolted from the head and bolted straight onto the DCOE
manifold. You then need to respace the bodies.

That (Stevebubs) is what I thought I was reading (into) this thread. We have a Suzuki dealer next to my place of work who didn't think I knew
what I was talking about. So if I get the base flanges that bolt onto the head of the bike, I can use them. Is there any disadvantage to re-spacing
the throttle bodies?
Thanks to all of you for your help and inspiration.

It's horses for courses.
Respacing the bodies means making / purchasing a new fuel rail (I used an off the Shelf Jenvey item - not especially cheap) and you need to be careful
when joining the spindles back together to make sure you don't warp them.
Be warned, though - the head flanges are blooming expensive - my local dealer quoted me £100 for 4. Scrappies want £25.
At the end of the day, if you're purchasing new rail (£60) and new flanges (£100) then you may as well get someone like Bogg Brothers to make
you up a custom manifold and mount as-is - it'll cost less and be far easier.
When I bought my bodies, I made sure they came with the flanges....

Out of interest, who else has this setup (or similar) working?
