You are talking lots of $$$$$$$$ fancy stuff like that if it WASN'T standard in the first place. All said and done, BIKE upgrade is often BEST / EASIEST horsepower getter. The GS... MAY... be the deposit on a half decent 600...maybe.
Rebuilds add little, or nothing (usually the latter) to bike value, and cost $$$$$
YOUR CHOICE

err, no. if you go up four teeth on the front you will have issues of the major persuation.

One up on the front is about three/four down on the rear

I didn't actually mean four teeth on the front. I meant that to achieve the result the OP wants they need to go up on the rear or down on the front.

i brought one from new...
got the 180 like frosty said.... then some

most simple thing to do IF you have the orginal pipes ( bet you don't) is to shove a long scewdriver down pipe... hit with hamer... this wil "unblock" the end of the baffle... letting it breath better... gave me an EXTRA 5ks top speed ( yes i tested it in a flying 1/4 we used to hold in nelson!! so i know this is true)
