This is the ADVmachines™ Jetting AND Pre-Filter AND Filter Skins PLUS the installation DVD solution for the 950 Adventure, Super Enduro, Super Moto. Includes 2 specific length hoses to vent the carburetor bowls that replaces the Y and also a flip top compact 4oz bottle of filter oil that contains enough oil for the first oiling of the filter. Refill the bottle with filter oil and take it with you. I will custom tailor each Jetting Package based upon your ship-to address elevation unless otherwise requested during the purchase process. What are "FilterSkins"? They are a package of 3 nylon "skins" that go over the Pre-Filter. They allow you to field "clean" a Pre-Filter by removing it and replacing with another.
