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 more than 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.
