I'm looking for a plain throttle body for an EFI conversion on my GL1000. This would be just to control air flow; the type you see on vehicles with multi-port injection. Anybody have one or know who sells them? I can find plenty of big ones, but nothing in the 38mm range except for one place where they won't sell kit parts, only complete kits. A little bigger is OK, but not much, 42mm max.
