I own a 2013 250 sx and wanna drop some $$ on it so I was wondering bout mods for it engine wise. I originally I wanted pc works pipe + 304 silencer but rode a sx '10 with the gnarly + powercore 2 and actually love it. Only problem is it's down on power up top and this is a problem I'd like to fix while keeping that exhaust. Was just wondering if this was possible with carby mods (oval bore, dicksracing carb,etc.) and a larger base gasket. Any other suggestions would be great too thanks.

Deck height, make sure you've got enough main jet, good fuel and go.

I have Eric's 295cc mid/top kit on my '10 YZ250. I'm very happy with it after a year of racing in the Vet B and Open B classes.
Consider getting a KTM 300cc jug and a PC Platinum pipe. That combo would give you more torque than a 250cc / Gnarly combo and more mid/top than the 250 with porting. From what I understand, the KTM 300 cylinder is a bolt-on deal for the 250SX.
The extra 45cc from the big-bore makes the perfect two stroke. You can run a smaller rear sprocket and it will still pull harder than a 250 out of corners. That means less clutch and less shifting.
