Welcome to the board!
Take a few minutes to familiarize yourself with the forum. At the top of every board there are threads that are tagged as "Sticky" These threads are "Sticky" because they contain very important/valuable information about the VTX and everyone should read them.
The thread at the top of the 1800 tech board called, "Air, Fuel, Motors..." will answer most of the performance questions...
Bookmark or save to your favorites folder, these websites, http://www.vtxoa.com/forums/73-how-step-step/
This is the NEW VTXOA Garage, a sister site to this message board and contains all your How-to/Tips/Tricks/Why’s and links to other helpful sites for your new VTX. http://tech.bareasschoppers.com/ A fellow VTX Riders site that has many write-ups on “How-To” do work on the VTX.
There is also a helpful Search button in the gray toolbar just under the VTXOwners Association banner titled "Search This Forum" click this then,
Click the “Advanced Search” button
Now, click "Search Single Content Type" and add you keyword to search
Select 1, and only 1 "Forum" to search in at a time, or at all.
For example, "Best airbox" I would only search in the "1800 Tech Board"
That's the basic way, you can limit further by using some of the other "Drop-Down" menu's like if you know the thread you are looking for is only a week or so old, etc....
The purpose of the "Search" is to offer a member the opportunity to research his/her question better. There is so much information from past threads that you may never see because that member is no longer here, or doesn't see your new post, or just won't respond to the same question. So use it to your advantage and enjoy the board!
