This one's for TB8100, Retro, and you other fellow Bad Boy owners. I want to change out/flush the coolant from my radiator on my engine. Any tips or advice on how to do this. I haven't looked closely at it yet, but am sure there's a hose or drain valve on it. Just wanted to get some advice before I went to the garage this afternoon. Also, what's the oil filter info on the engine so I can go to Autozone and grab one. Thanks. Also, refill with half and half like a truck or what???
