Wow, very nice ride! I too just picked up a 2002 America, this is my first Triumph... actually sold an '86 HD FXRS a while back and was looking for a Bonneville T100, but came about an America...love it,as I'm sure you will.
I found a service manual on flea-bay for 35 bucks last month, I know I got lucky with the timing, but I'm sure there are more available used if you look... or pay $100+ for a new one ...
How many miles on yours....mine had about12,500....
