The cost of aftermarket throttle bodies is way up there, the bottom of scale we have the CB Performance units which are about $250 each and the rest are easily 2X that about.....

so I swung by the motorcycle salvage yard in Fremont today and picked up these beauties (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

45mm at the butterfly....they taper down to 42.5mm at the bottom...

includes a nice TPS and injectors...I doubt the injectors flow enough, but who knows, I'll find out once I get the specs....

no idea of what bike they came off of yet.....price was $125

Mike,
Pardon me, I am going to show my total ignorance here. These are a great idea....but what FI system are you going to be using them with?
Would this setup work with a stock injection?

Nomex is now on.... (IMG:style_emoticons/default/welder.gif)

It almost certainly won't work with stock injection since the MAP (Manifold Absolute Pressure) profile will almost certainly be different due to the short intake runner and lack of intake plenum.

Sorry! It ought to work well with a megasquirt though - although might require some cleverness to get it to work well....
