hey all, i have decided to clean my headers due to loss of lisence

it's an '06 636 and is there a way to get them off without dropping the coolant......i dont really want to but if worse comes to worse then i will.....i have already got most of the fairing off(except for the top fairing....figured i have to take it off with the lights still attached!!)also any ideas that i could to the bike while it's off the road?
