Yx 160 mods

[Mxr160]

I've seen all these big bore kits and v2 heads etc but I'm on a really tight budget to get a quick bolt on power mod, I've got decent suspension and tyres already so now looking for more power, is a oso 26mm carb the best way to go to get a bit more pull out of it? Will it need much setting up or just jet nd go? Any suggestions
