butterfly is a metal looking deal on the inner part of the throttle body....you "open" the throttle and it allows for more air to come in..closed you cant see down the TB.....and by fluid I mean non restricted movement...shouldnt hang up anywhere in its travel from fully closed (off position) to fully open (wide open throttle)
keep your ears close to the TB's (throttle bodies) and see if you can hear anything at all scraping or if you can see anything getting hung up.....that would be were I would start looking myself....sounds like something got a bit jarred and maybe hanging up some.
sucks to hear about your crash man......gear is your friend...wished I woulda had my lid on when I went down because I took a solid wallop to the head from mine...lucky I didnt fock up my brain any worse than it is already.
and no need to be saying sorry...thats what the forum is about...asking questions and getting answers and making a few friends along the way.
