To answer Lil-Steave, I do not necessarily recommend doing this as it could create a problem. I have been doing it for many years and four different machines with out any issues. On one UTV I was able to remove the tube altogether. But was unable to on the Talon.
But I only fill to that extreme when the ride dictates the need. When I get my new 10 gal. tank I will not make the mod in it.
After the the first 15 miles or so I am back to stock full at 7.2 gal. and that don't take very long time.
Should you decide to try it. You must be careful that you punch the hole in the tube below the where the filler neck attaches to the top of the fuel tank.
Should you miss you will be replacing the tank.
I would not recommend using a drill and if I where too do it, it would not be any larger than say 1/8" - 3/16". But I do not like the Idea of any material falling into my tank. As for the hot rod it would produce the best hole, but as mentioned might not be the best or safe way to go about it.
I make my vent hole using a 1/4" wide very sharp wood chisel. It pushes a hole in the tube with very little effort.
Once the hole is made, rotate the chisel several time to make the opening stay some what open.
Once the fuel is added to the tank and reaches the stock fuel full level, you will still need to add fuel at a reduced rate to allow the trapped air to escape.
As for any fuel vapor problem at the filler cap, I do not see how that could happen as the cap and filler neck is not vented there.
For me I like the 10 gal. Tank idea. And from the diagram and explanation by PaulF, It looks to be a pretty easy job to install the 10 gal. tank.
