Looking for confirmation on the following interpretations before I spend money on gear I can't use in Production Class. For bikes, though it may be interesting if the first three are allowed in Prod for cars but not bikes;
O2 sensor(s): I am guessing not allowed as it would not 'appear' stock
Shift Lite: I am guessing no due to the appearance issue again
Data logger: I am guessing they are ok as long as they are hidden from view
Clip-ons: The rule allows different handlebars within a set of specs but I am not clear whether that applies to swapping clip-ons. I believe that is ok, within the same specs, as long as the bike originally used the same clip-on style/mounting point. In other words, no swapping handlebars for clip-ons. I also believe clip-on changes are not allowed at BUB in Prod from what I saw in the AMA rulebook.
