Hi all,
I've seen a few youtube vids about modding the secondary butterfly valves on the FZ1 (I have a 2011 version) and wondered if this was worth doing and what the effects were, both positive and negative.
I currently have the tank up while doing some other work and will be balancing TB's so thought this could be a potential mod.
It sounds like mid range is boosted as the air is made available quicker, which sounds great but does this affect mpg (which I really don't want to drop any further if I can help it).
The vids show the 'flies' being trimmed, but I thought surely just removing or opening fully and inactivating would be easier, or is this too much of an effect?
Anyone done this mod and thoughts on the effects to an otherwise stock bike.
Cheers.
