But...... the 575 is "blueprinted" the rest aren't. Also when you go to resell it the stock blue engine "should" bring more than the modified black engine. And the 575 is built as a blower motor so if you want to get more power I would hope that an intercooler and pulley is all you need as opposed to new valves, gaskets and so on that are "recomended" when supercharging a black motor. Not that you have to add these things.
Sometimes perception is more important than reality.
I also promised Jo I wouldn't ever tell what I paid for my upgrade from a 500 to a 575 with ITS and XR..but it is waaaaaay less than what gets quoted on say a fountian web site or the difference between what is quoted between the "list" prices from BAM or a number of other resellers.
