You would port the cylinder. And yes, huge gains. Rick at RCR can help you out.

If it's a 2-cycle then yes, porting the cylinder would be worth as much power as the pipe itself made. The gains aren't quite as prevailent on the 4-strokes, but it still does help. I only said that because you didnt say whether it was the 400 or the 500, but seeing the HPD trail pipe I would assume it was the 400.

you can lighten the fly wheel and still keep your electric start with the trail lightening...and it will help your motor build rpms faster but i think it takes away from your low end grunt.."there is a give and take for everything aint there"...

Reit38, with the other mods that you have getting your jug ported and your head shaved would really wake your 400 up. I also had RcR lighten my flywheel while he was doing the other work. I don't know how much it helped but I don't regret having it done.

Send it to rick or bubba for the port work.
HPD is an excelent company, but I think these guys can give you more, bang for your buck
