TE/TC Help with TE300 gas tank

Hi Guys,
I am irritated how Husky has in the owners manual the gas tank listed at 10.7 L or 2.83 G. Soon after I got the bike I drained the tank and filled it up using a 2 liter Coke bottle. With the bike standing up right, I marked the level on the tank with a sharpie after each 2 liter bottle added. The tank was fill after a little over 8 liters. The manual says it takes 10.7, so I thought I had somehow forgot to mark the tank after adding a bottle somewhere mid tank. I did not feel like draining the tank and double checking, just put it down to a senior moment and left it at that. I thought I had read somewhere on this site someone had stretched their tank and now holds 3 gallons. Decided to stretch my tank as a decent ride I would use a whole tank plus 2 two liter Coke bottles of gas and barely make it back to my truck.
With the tank empty and in place on my bike, I filled the tank with boiling water let it sit for about five minutes then pressurized it. It did not hold much pressure before the air escaped from the gas cap. The tank expanded mostly on the larger side with the petcock. The next day I laid the bike on it's side and only filled the smaller side with boiling water and pressurized it, hoping to get the tank a little more symmetrical. The end result the tank does not look too bad. It is a little wider, you can feel it when siting on the bike.
So I was hoping for about 13 liters (3.4 gallons) as I thought I was starting at 10.7 liters. Filled the tank again using a 2 liter Coke bottle and marking as I went. To say I was unhappy and disappointed would be an understatement, when I found the tank only holds a little over 10 liters. Made me start thinking how much does a 2 liter bottle hold, so I measured and found I was over filling the Coke bottle a little each time. So I am thinking the tank holds about 10.5 liters (2.77G).
So my questions are.....Has anybody on this site stretched a TE300 gas tank so that it actually holds 3 gallons. If so what did I do wrong?, I even added a rubber gasket made out of a bicycle tube to the gas cap so I could add more pressure. Does anybody know of any after market tank that will hold 3.5 to 4 gallons that will fit our bikes.
If somebody can tell how to add pictures, I will add some.

Thank,
Sean.

Simple solution... Aftermarket tank for a late model KTM and some white KTM radiator shrouds. Craig Delong ran this combo, with PG graphics.....

those checks are embarrasing,,,,,,,really

WTF!!! Buy a bigger tank! Simples!

The "A" classes don't get paid at a gncc unless you are top amateur.

I think there is a missing zero at the end...

IMS is making the tanks. John-Erik said no to any of the factory teams using KTM tanks and shrouds, irritated with us apparently too.

Husky USA under BMW was just as slow getting tanks for X-Lite and 125's in '09. I spent a good bit of my time and money, trying to move the process along with P3 to no avail..... Had fun with Lindsay Pirie, cool guy!

Hey man, if you were a C rider and lived 1/2 mile from the track you could almost pay your fuel and entry fee with that massive check.

I'm in Aus and found the exact same issue I went back to husky Australia and said it was false advertising and the 10.7L tank is now on it's way to me. Seems that Australia isn't only country with issue

Parkeshusky, do you have to send your old tank back after you receive your new tank? The reason I ask, I've stretched my tank already. I think I'm going to try contact Husky USA. Hopefully I will get the same results, see what happens.

Assuming the Husky tank is the same as the Husaberg, apparently a Acerbis KTM will fit with minor seat trimming. http://www.cyclebuy.com/shopping/gas_tanks/husaberg_2stk.htm#Availability_Guide

I'm really curious, what tank Husky Australia is sending Parkeshusky? Were some tanks molded incorrectly and now they are right? It will be a big bummer, if the new tank is the same one.....

that cheque would have had to of cost at least $100 to make wouldnt it!

OK OK I'm having a Te tank installed on my etc. Is this a stupid move??? I thought the Te was rated at 2.9 gall????? Am I wasting $200????
