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)

Group: Members Posts: 17,150 Joined: 4-January 03 From: Antioch, CA Member No.: 87 Region Association: None	QUOTE(Randal @ May 25 2005, 01:58 PM) Mike - Can you make adapter 2 out of the same metal as the TBs and if so couldn't could you just bronze or weld the two together? I've thought about welding them on the very most bottem section, but I only have a MIG which is not set up for aluminum and I don;t think I trust myself using my oxy-acet. setup (IMG:style_emoticons/default/welder.gif) TIG would be best but they'll still have to be positioned darn near perfect..... brazing might work, but I still would worry about the heat since the walls are pretty thin on the TB's Andy, Pro/E...drawing not as pretty as it could be, but I'm trying not to spend too much time on this project....
