Hi Mike, from what I can understand the pods will restrict air flow through the carb less than the stock airbox/filter combination (plus there is the "looks" effect), hence you get more air into the carb, this requires the carbs to be adjusted, this could be larger jets or changed needle position, or both. You will have to check to be sure, I don't know anything about the 550 so cannot advise on stock jetting. It will also depend on the exhaust system fitted to the bike, the less restrictive the exhaust the more airflow, the more fuel is required, though unless your exhaust is wildly noisy I would think that stock jets would suffice.
Cheers
