They offer their version of an airbox as an option to traditional individual pods. Like using pods, and changing from the stock airbox, jetting changes will very likely be required to achieve the best possible tune for your carbs. Physical fitment changes and such to the actual carbs themselves, won't be required. This is a plenum style change, not a carb mounting change.
Is that a bit more clear?
A little primer for you as to why you will encounter member positions on carb changes:
- Your engine is a large air pump. Changing a single aspect of that "system" ie, airbox, filter element, exhaust baffles, pipe lengths, changes the performance of the "pump". It is widely agreed that the stock configuration, for all it's possible faults at peak performance, performs best.
Many new owners, like the appearance of pods or their build/customization benefits from the look of pods. And many who choose that route, feel their engine performs "perfectly well to their opinion". Maybe, maybe not. It is indisputable that a dyno evaluation of a stock system versus a pod-equipped system will identify changes in the performance of the "pump". You can tune the pod-equipped system to perform well, but probably you can't tune stock carbs with pods and exhaust changes to perform "as well" as a stock induction system.
So you have 2 schools of thought here: "stock and why would you ever change it" or custom and "because I'm happy enough with it". Pick your school colors and set out to build your bike that you're happy with.
My recommendation: always try to arrange a dyno tune for every bike you rebuild. Even stock settings can be improved, and only a dyno will truly divulge the correct adjustments.
