you can definetly break 50 with a cam and piston, you were right at 50 jodi with your web 490 and cp and your xx was the lowest # i have seen for any xx with the big 3. I have had them at 48.5 with just the big 3 and usually they dont do less than 46.5-47 there is some varience from bike to bike.

A piston alone will not gain you a ton of hp though maybe .5 to 1.5 you need to change the cam to net the bulk of power. I wouldnt do a piston alone unless you needed to for repair issues or just wanted to get it done while you save up for a cam.
