So these ITB's are the ones Lindsey used on their system? And I thought they had finally made something of their own.
I must have given them too much credit.

I don't know what it is about those but I don't like the look of them. Maybe they work well enough, I cannot comment, but I have never been a fan of anything with a "universal" fit. Also being extruded you cannot get them with tapered bodies, and those linkages with the little grub screws connecting the shafts together, I fear their simple complexity.
I would rather go with a trusted design with many options and proven linkages, such as these: http://www.jenvey.co.uk/drawings/sf0_bw.htm

Using a base cut from a stock manifold and Mandrel bent aluminum 90s from Burn's Stainless (cut from 180deg bends) allows you to put the throttle bodies horizontal for hood clearance and use stock type injectors.
I have all the parts to finish the project but....too many irons in the fire.

Port size is a very close match on the Hyabusa set.

My other concern is how much boost can the 'busa TB's hold...stock or aftermarket.

Jesus. That'll be a monster. I would be very interested to see before/after dyno results, but I think with some decent fabrication skills and machine tools it would be a nice winter project. If only I wasn't sinking my life's fortune into my 951 currently... :'(

I suppose I mean that they at least look like a stock throttle and designed and made from similar material. Also that they have injectors, throttle plates and linkages built into the design and not just stuck onto an piece of extruded aluminum. I am sure those extruded designs are fine, it's just I don't personally like the look and design of them. (IMO)
