Cool if you like bondo
Was so excited to get new tank, until i received it. There are many deep scratches, ripples in the metal (which i wouldnt care if they were only on bottom of tank), many chips/pits, and the seam running down the middle is a mess. I have to put a coat of bondo on the whole tank just to even everything out! It is a nightmare and not what i expected from brand new tank! Look/ shape of tank is cool, but have so much work to do to it, dont think it was worth it.

Great value
With few modifications, this fit on a 1999 1200S. Very little body work needed. Really made my 'girl' look even faster.

nice lines
My only objection is that the picture looks like the tank has a design on the side, and the tank is smooth.

Under thank there's three small tubes made on tank one is s vent tube , one is closed off or solder closed , on the other side is one , what is it for ?fuel of another vent?
Chad A on Aug 5, 2016
BEST ANSWER: On my tank I have a tube connecting both sides of the tank. Both nipple so we're open. This way the gas evens out as the gas level lowers. I think this is because the tank is divided by the frame when it is mounted. Meaning 2 sides of the tank straddle the frame and you need this connected to get the gas from both sides. To open the nipple you should just be able to heat it up with a propane torch and melt the solder out. Then connect both sides with a short piece of tubing and 2 small hose clamps.
