xc so i need more low end

a 10 dollar sprocket could give you a ton of bottom end. if thats all you need. It would shorten your gears though.

port work is big power gain but if your gonna rip the head off to get it ported put in a hi comp piston and retard the cam, go after market cams if you can afford it. Methonal is good for a few easy pones too, and it runs way cooler than regular gas.

i don't know about xc motor sizes but you could also get the 3mm stroker crank for about the price of a good port job and have a torq monster.
