My question concerns the TORs for the T100 Carb verses the TORs T100 EFI is there any real difference in the pipes themselves besides the fact that one requires a jet change and the other requires a down load/ remap, and the part numbers. Are they interchangable or what? They look exactaly the same to me. I am looking to fit one or the other on my 2008 T100 carb, and I can't seem to get an answer anywhere and I hope someone here can set me straight. Thanks.
