The spare set of carbs from Phil came in the mail yesterday. They are making my lab smell pleasantly of gasoline and solvent. One of my labmates is also a gearhead. He’s loving it. The others aren’t saying anything yet. I guess that gas smell hasn’t traveled all the way down the lab.
Taking some measurements from the carbs, I found the following:
Throttle body outlet measurements:
- Outer diameter: 40mm
- Inner diameter: 37mm
Throttle body inlet measurements:
- all wonky because they are tapered to receive the plastic airbox
I’ve been poking around looking for 37mm inner diameter throttle bodies with sensors and fuel injectors already installed but have come up short. It seems like the Moto Guzzi Breva 750 throttle bodies might be the right size. There is an auction on ebay for a set. They have a sensor but don’t have any injectors as far as I can tell. There is also a Suzuki Burgman 400 throttle body that ebay indicates might be the right size. Looking at the microfiche, the Burgman does have fuel injectors. I wonder if anyone on the IPCRC might have an extra set laying around… The microfiche doesn’t tell me enough to figure out what angle the injector body is at compared to the throttle body and if the throttle body has any strange turns like the fuel injected VT750 throttle bodies do.
My google-fu is obviously weak because I haven’t had any luck finding a list of throttle bodies for common vehicles and their dimensions. Does anyone know where I might be able to find such a list?
