I have a 2004 Dyna which I am going to take out the cam support plate & oil pump, I believe there are about four O rings in there - one of them is supposed to be yellow color from factory, when you get a replacement one is it yellow or do you just get a black one. Supposedly this yellow one has a different texture to it, so if anyone knows anything about this it will be appreciated.

thanks for your help once again Scotty, it took me three dealers in WA to get that yellow O-ring, but i finally got one and am about to start my cam swap and gear drives thanks for your input

You'll love the difference a gear drive makes. With mine, the bike just wants to spin fast. A little bit rough, but that's the nature of the beast. Offers great touring ability and plenty of punch up hills.

Scotty are those part numbers the same for my 03 ultra as am going to fit the 203 cams in the new year.Tks for all your help in 09 looking forward to your comments in 2010 and the brake pads are terrific.Charlie
