I tried digging through old threads but to no avail, has anyone tried to put an aluminum version of the fuel tank on a v7 iii? I'm interested since the stock tank is pretty heavy and I could see some potential weight savings.

Doesn't exist, but if you mean the 70's V7 Sport tank, nothing would fit or work as to mounts, fuel pump, gas cap, etc etc.
 
Okay so a custom fuel tank would have to be fabbed.... any good recommendations?
I have guys that can do it, but you're looking at ~@$2000 without paint to do one.

got it. most aluminum fuel tanks are in that price range, so no big surprise there. Very well, once i recover from the big bore kit that will be next in line.

And I would be surprised if there was much difference in weight.
Plastic isn't much heavier than aluminum. The stock tank is probably so heavy because of the fuel pump and whatnot in it.
I do like aluminum tanks, But paying to have a custom made aluminum tank made expecting a big difference in weight will probably be disappointing.

I've held the fuel pump with my hands and it doesn't feel heavy at all. i've carried the oem steel tank without fuel and pump, I can tell you that it has some heft to it.

If you really want an aluminum tank check out Evan Wilcox, he can make one but you will have to wait for it.

Mebbe I am misreading your post. T

Certainly true re plastic v. aluminum, but his III has a steel tank.

I can't see the co$t of a cu$tom alum tank on my EV or two V7's, as if I were that serious about weight loss, I'd eat fewer pancakes! :giggle:

Now, my plastic tanks on Griso and Norge ... grrrrrr. :swear:

I don't know which V7's have steel tanks and which have plastic. The tank on my Lario is steel. And it ain't that heavy (no fuel pump).
Most steel tanks I have seen didn't weigh more than five pounds. They are hollow, after all. An aluminum tank should be lighter, but even if it weighed nothing you couldn't save much weight on a street bike by switching from steel to aluminum. So, spending that much money on an aluminum tank to save a few pounds seems kinda extreme for a street bike to me. Kinda like swapping to a lithium battery to save weight on a street bike.

I wouldn't doubt a small tank would way five pounds, but there's no way a v7 steel tank weighs that much.
 
How did I miss this thread :drunk:
Maybe He has Too much money... burning a hole in his pocket..
Buy a Racer or Special tank?

But then again I had a custom tank built for my Honda, because I couldn’t get more than 60-70 mile before I hit reserve !!!
Now I can go over 100 and have even more on reserve !

Regarding an aluminum gas tank, be careful about how its mounted if you intend to use it for more than a dozen or so races. Aluminum material will fatigue even at stress levels below its minimum yield strength. So the mounting provisions for an aluminum tank should effectively prevent any vibration from reaching the tank.

An alloy tank has the advantage of eliminating the chance of rust forming on the inside, and I've seen various vintage tanks where once the rust was removed there was only a lacey panel of steel left.

Evan does superb work and you will pay accordingly. But if you are handy with tools it can be fun to try and make your own tank. For the price of a purchased tank you can buy LOTS of aluminum sheet and metal bashing tools, and the alloy sheet can be either TIG or oxy/fuel welded.

Here's a tank I built for my Laverda 750 racer and another on my Honda 216 racer. Yes, they are "race" quality, not show quality, but they worked and were my early attempts at making a tank.

cheers,
Michael
