Jetting with new pipes and box

[miashee]

I switched from cpi's to fmf sst's i wanted a better trail pipe. I also ride in dirt and muddy trails so i switched to a box with no lid and a proflo intake setup with just one big filter instead of the two k and n's that were on each carb. Im not sure what my jetting is now but the bike did run good. The fmf pipes i got came with 260 mains. Should i put these in or just run it how it was when i got it and do a plug chop before i change anything.

what are your general riding elevations and temps? are you using an aftermarket filter? Ported?

After market filter, sea level, not ported and mostly trails.

any suggestions?

I'd start with a 290 main, 27.5 pilot, see how that does...if anything it should be a hair rich. Definitely do a plug chop though, that's the sure fire way to know if your jetting is accurate.
