Hi all,

I have a question that concerns me. I have a stock XT660X with a set of Akrapovic slip-ons with no air mods. I took out the db-killers from the exhausts and I'm wondering won't the bike be too lean now seeing that the pipes are practically open pipes? Won't I need to enrich the mixture a bit or is it ok to leave the bike as is?

Thanks for the help in advance,
