fastdude, thanks for your input.
Cowboy, some of the old literature said the thrux would have higher compression than the bonnie, but it does not. I've also found that the dealers usually know Jack Sh!t about anything aftermarket, at least mine does. He also had the gall to tell me that 865 cams are better than 790 cams! My guess is b/c the Triumph literature said "the thruxton has hotter cams".
Nonsense!
