New project:Adapting motorcycle Throttle Bodies, this should be "interesting" :) Options

[Mueller]

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

Cool. I'm doing the same thing using Suzuki GSXR throttle bodies on a Ford Ztech engine going into a Lotus Seven replica. If you want to see some other people's projects check out some of the links in the thread at :

They're ricers, but it all works the same. You're right that the big boo is going to be the linkage. It's lots easier on an inline engine. The common way to get them onto manifolds is using silicone hose and clamps on manifold stubs, the way they were attached to the bike motor, but that won't keep the carbs rigid enough to keep them in sync using VW/914 style manifolds. You might want to check out using dual carb type cable linkage for a BMW R-series motorcycle or, if I remember right, some older British sports cars like Spitfires and TR-3's. Seems the cable might be easier.
