Replacing Intake/box with aftermarket filters.

[Water Warrior 2]

I think that Jonathan was trying to say that a pin hole in the intake will alter the engine running more than a hole in the exhaust system. Even a pin hole can upset fuel metering and cause issues to an otherwise fine running bike. My own personal solution is to leave it alone. Suzuki pays some pretty smart folks a reasonable rate for making things work over a wide range of operating conditions. Bone stock the GZ is a fine bike. Lynda had zero issues riding bone stock and the bike proved it's worth in all weather conditions encountered. I know a lot of owners want to change the bike's appearance or whatever but I stick the idea if it ain't broke don't fix it. Been there done that. I'd rather ride than tinker.
