I just bought an 04 Road King and would like to see what everyone is using to clean the black parts on the engine. Can anyone help me??

Lot of my buddies use S100 cleaner to clean engines. Works great, but word of caution, don't spray it on hot motor or let it dry before you rinse it off.

S100 cleaners are the best I have found so far. Great recommend WORK! How the hell you been by the way???

I have been good, at least nobody has told me any different. Just waiting around for the weather like everybody else that comes in here..............

I've found that the car wash pressure sprayer works great.

I use a product called "Pig Spit." I get it from my Harley dealer but I have seen it for sale on the net. It's expensive ($13.00 - $15.00 per can) but I haven't found anything better. Spray it on after you wash your bike and your done (no kidding!). It really makes the black wrinkle look new again and it lasts for a long time. It also works fine for every other surface on your bike except of course the tires (might make that first corner interesting).

Murphy's Oil Soap spray cleaner works as good as S100 & leaves no residue at all.
