Jetting carb for FMF pipe!!HELP

[ocassault]

I tried some searchs but one person says 240-250 and one says 270-280, my blaster is pretty much stock except for tires, bars and so on, I have a new FMF gold series pipe and would like the proper jet kit I should buy, I dont want to run it without jetting it and do I just need to change the main jet or all, any help would be great! plug seemed fine w/ stock pipe, dry not white!

like u have read in other posts it all depends.elevation plays a huge part in it.stock is 230 so go up from there the higher the richer i think im not an expert.
