airfilters on Bike throttle bodies HOW?
I'm stuck....
I have replaced my twin Webers with Suzuki GXRS 750 throttle bodies. engine is running with MS II. :-)
i'm stumped though, on how to attach airfilters to the TB's. There is only a smooth circular tube to attach anything to. The Webers have
lugs, to attach the filter backplate.
Ideally i want to reuse the airfilters that where on the Webers. Because: i have them :-) because they fit in the bonnet opening, and lastly because
then i can then also secure the velocity stacks. ( i made sure that the inlet length is the same as with the Webers.)
any ideas, thoughts advise.... greatly appreaciated!
thanks! Pieter

Well I'm going down a different route with my trumpets by DIYing...
I've got some wood lathe chisels and a bench drill and a big chunk of cherry wood- it may all end in tears 
I've also got some GRP tissue and epoxy resin waiting to be fabricated into dinky little trumpets off the cherry wood mould (or is it a buck?
still reading my GRP book!!!)....

strap to back plate

I used the rubber trumpets from the GSXR air box....The two inner ones are longer, so I ended up buying an extra air box from ebay (about 20 quid)
this meant I had four long trumpets, and four perfectly sized rubbers to attach the throttle bodies to the inlet manifold.
I ended up chopping the 'holes' from the air box which of course fit perfectly over the trumpets, then sticking them with Sikaflex to the
back of the back plate for the filter.....
This shows the trumpets:

You can just about see the plastic I removed from the air box on the bottom of this one:

Thanks for the replies. (sorry for the delay, but work has come in the way of pleasure, once again :-( )
I'va been phoning bike breakers (not many here in Holland) for airboxes, none had anything likely to fit.
So i've decided to fabricate adapters myself. i will make up some, short, ally tubes (thick walled) that will slide over the bodies, using an
O-ring to seal them. I will clamp them with a hose clamp. I will make 4 cuts so it WILL clamp. I will make a back plate for each TB. to which I can
attach, the backplates of the aircleaners, i have left over from the Webers.
the thick new back plates will allow me to use the original clamping bolts, to fix the ram pipes.
Make sense?
I will make some pictures as i go along.
Make Sense?

I used the velocity stacks from the bike (GSXR) these fit into a backplate like a grommet... Works very neatly and not much movement.
