All 05's came with E size carbs and restrictor plates. Stock jets were 28/72. Most have removed the restrictor plates and some have converted to the G Carb.
I'm still running the E Carb that has been bored out by xXX carbs and I'm running a 29.5/74 set of jets with restrictor plates removed.
You need to tell us what you have before we can advise you
