I changed them out almost 2 years ago shortly after buying the bike.
I have ridden with 18's on my old shovelhead.....and to be honest with you I find the 10's may not have the cool factor the 18's did. But I sure enjoy riding with them a whole lot more.
I found the cables and hoses on ebay....
Bottom line is it looks good,they are great to ride with,it was a cheap swap and I like em!
