"There are some things nobody needs in this world, and a bright-red, hunch-back, warp-speed 900cc cafe racer is one of them — but I want one anyway, and on some days I actually believe I need one....

Boil some antifreeze and drop your valves in. Takes about 15 minutes to come super clean.

If you do this be sure to do it in a well ventilated area!  Ethylene Glycol is extremely poisonous and will damage your kidneys.
