I'm looking for a small size injector, in the 12lb/hr range. I have noticed that people are using Keihin injectors but I can't find any dimensions.

Thank's, Keith

I have found some smaller injectors but the flow rates are way too low for my app. .

Does anyone have flow rates and operating pressures for the injectors on a 250or 600 sport bike? These injectors look like they will work.

I cant tell you what the flow rates are, but I can tell you that the size of the injectors on the GSXR 600 is about half that of my stock Honda Civic injectors.

thank's, great info, there are some flow rates for the gsxr 600 on this page as a sticky. they are double the flow I need but the right size physically. I think I am going to try them and just run a lower FP.

I calced. about 18P.S.I., will that be a problem?

I cant tell you the flow rates but the cbr 600 rr runs 8 injectors two per cylinder and on is close to the valve and one is in the air box. I imagine they would flow very little espicialy the primary injectors (the set right by the valves) It runs on those 4 under light loads!

thank's guy's, the CBR injectors might be what I need.

Do you know what year they started running 8 injectors?

The mini cooper injectors are the right size but the flow is 3 times what I need.

About 120cc is what I'm looking for.

Does anyone know of an F.I.'d ATV? most of them are 2 cylinder.
