installed 70 degree tank

Sub tank info
Received 70degree sub fame tank a few weeks back
Very good workmanship with the tank and aluminum parts, Iíve paid more for specialty small aluminum hot rod parts than this complete tank cost . It is a good buy for the work that has gone into making this tank.
Before installing read instruction will make job easy
Check and clean all threads built into tank use supplied fasteners to check threads.
Follow instructions, instillation takes about two to three hours at a careful and thorough pace. Take your time and do it right itís worth it.
As most of you know, donít use a one way check valve on the vent hose, if you ride slow nasty trails on hot days and the fuel percolates (boils) you will have problems if the pressure is not vented!
Sub frame tank weight is within ounces of the stock sub frame thatís good
I put exactly 3.25 gallons in and I had room in the back of the sub tank for another 2 tenths of a gallon but did not want to over fill the tank and I would have had to raise the front wheel a little, was not worth the effort, I was very pleased with the capacity of the tank .
I donít have to carry fuel in my back pack anymore, my lunch and snacks will tasted like food not gas.
Check your rear sag might have to tighten the spring one turn. Fuel weight is a little over 6 lbs per gal so you might be ok but doesnít hurt to check.
Bike feels great on tight trails with the sub tank you donít even feel it, much better than caring the fuel high in a big tank. If you are going for a short ride just put a small amount of fuel in, splits between the two tank now its like a world super bike, fuel is chambered for less movement (slosh) and the fuel is carried lower on the bike ( this info is for you WFO guys)
Thanks Dale and others for all the hours you have put into this
Now the bad NEWS
When you come home at two in the morning the wife wonít believe the old I ran out of gas story.
Have a great ride

Your story will be more believable cos you will run out of fuel even further away than you would've before!

Great write-up!

Re: installed 70 degree tank

I have just installed my new 70 degree tank and was very impressed with this product. I was a little bit taken back by how much fuel I had to put into the bike before it would start. Was around about 1.5 to 2 liters before it fired up. Has anybody else noticed this before as it's starting to make me think that my fuel pump pick up may not have been installed correctly.
The next step will be to unplug the fuel line and see how much fuel comes out as maybe there is always 1 to 2 liters that just goes along for a ride.
Any thoughts on this would be much appreciated.

There will always be some fuel left in the sub tank as it is below the fuel transfer point.

If you unplug the quick disconnect nothing will come out, as it is a double sided shut off when it is disconnected.

When you put 1.5 to 2 liters in the bike, most of that MAY have ended up in the front part of the main tank, and very little may have made it back to the sump where the fuel pump is. This fuel that resides in the front part of the main tank usually makes it way back to the sump area under normal riding conditions as it splashes around.
