Default TB size??
Just trying to get it right, Is the throttle body size on the '09 96" fat bob 46mm and 3.9gps injectors??
Wondering if i should change it out when i put 103" jugs/pistons on.
Im doing a fuelmoto 107" build on wifes TG and putting TGs 103s on my '09 fat bob. Using the cams, etc in my sig.

I got the se 103 stage4 kit and love it. It came with the 58mm TB's and high flow injectors. I went with Harleys kit because it came so complete and took the guess work out of every thing.

Can't answer your question, but I can say that is one way to kill two birds with one stone.....upgrading two bikes at the price of one!

Just found out for sure that the stock TB is 46mm with 3.9gps injectors. Should work fine for the 103" with polished and ported heads that im doing.
