914 Freak! Group: Members Posts: 17,150 Joined: 4-January 03 From: Antioch, CA Member No.: 87 Region Association: None	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 top view: Attached image(s)
