I purchased a pair of used throttle bodies.
My plan is to clean them up, send the injectors out for professional cleaning and eventually swap them onto my R1100RT (currently 100k miles). So, I don't have a parts washer or ultrasonic cleaner. I've got an aluminum roasting pan, simple green and any other bottle of cleaner chemical available at the local auto parts places. What's my best choice to get these cleaned up. They are fairly grungy both inside and outside.
