Please bear with me I'm still learning when it comes to Fi, I always thought it was a straight forward affair ot: Anyway so removing the air filter I see the bike has a PCV, lift that and then I found another Dynojet Autotune unit below it. Is this the noraml setup to have on a Z ? The bike has aftermarket pipes and snorkel removed (DNA filter). There is a magnitude of wires from all the units below the seat, are they really needed in your opinion ? The bike ok (have not ridden others), it pulls ok and there are no flatspots and very few backfiring.
