for the record, that post was not directed at you. It was more for the guy running a sock on the cooling head. and im not insulting ne one, or trying to ne way, its just that engines are affected by weather, but the tuning can still be done for optimum performance, i guess in EXTREME sub zero conditions, it might be extra difficult to get it done, that i dunno, have no experience with any engine below freezin, i live in TEXAS hahah
