Metal Tank for an S2R

[ducpainter]

Beyond physical interference issues, which vary by which Monster you're talking about fitting a steel tank to....

The rear hinge arrangement is different, so you'll need that assembly.
The fuel pump and fuel filter from the plastic tank will not work, so you'll need the steel tank style parts.
The fuel level sender and fuel pressure regulator are integrated into the plastic-tank fuel bulkhead, so you'll need the steel tank style stuff too.
You'll need to re-do the fuel lines, as there aren't the quick disconnect fitting on the steel tanks, and you'll have to mount the external fuel pressure regulator.

Fuel filler cap is the same, but you'll need the mounting ring.
The rubber pads that sit on the frame are the same, and the latch is the same, so you can recycle those.

I fitted a CF tank to an S2R1k for one of my customers.
The CF tanks are set up just like the steel ones.
For all the parts necessary to do the swap, if you start with a totally naked steel tank, it's upwards of $1k for new stuff.

But can be done...

WHOA........

$1K just for the shit needed to convert is even more of a reason to get a tank custom made and then have him mass produce and fleece everyone else too  

I'm going to connect with the folks in MA this weekend and potentially send up a tank for review and potential work to create a alum. one.  

We shall see how this experiment goes....

is it too hard to find a complete metal tank setup from a wreckers? then all you need to do is the fuel lines/regulator (which could come from the same parted out bike) and the hinge arrangement..

in the for sale section there is a 620 being parted. i think it would still have all the parts needed, could be a god send to you!?

p.s. it looks like it might be a plastic tank... i cant see the lip that runs aroung the bottom of the metal tanks in his pictures

I saw the 620 for sale which is interesting to me, however, I'm not knowledgeable enough and no one can confirm whether if I swapped out the my S2R tank with a 620's tank using the fuel lines, hinge and reg, whether my bike will work well or not.  Is it simply a matter of taking a 620 with all the hinge, fuel lines and reg and connecting the new fuel pump to my bike and presto the bike works?  Or will I have to purchase the 620 and all the necessary parts and then a couple of hours at the shop to make sure everything works?  Any guidance would be awesome. 

However part of me would like an S2R specific tank.....Maybe others can get one if there is a guinea pig

I have no proof...

but if you get a complete tank off a wreck...

and the external regulator...

and the hinge pieces...

and plumb it correctly...

it will work.

I'll put money on it.

Here we go then DP. Let's see where we end up.

Here we go....

620 tank hinge pivot purchased (CHECK)
620 fuel pump and filter purchased (CHECK)
620 tank is next (in Progress)

What else am I missing?

he doesn't have all the necessary parts and the tank is plastic.....But it's a good thought.  Starting this project we'll see where we end up.

it sounds like tin tanks are getting a bit harder to come by, i have a spare that im cutting up to make it even cooler tho 

only question i have is the fuel pressure. from what im reading the plastic tanks have an internal fuel pressure regulator, and mine (the tin tanks) have an external one. are they both the same pressure? if not then it would effect the tune...

So I've got a lead on a steel tank after calling around to a dozen junk yards on the WC, they are becoming harder to find.

Roaduser - The fuel pressure is the one thing I am very uncertain of.  I don't know if it will generate the same pressure nor do I think anyone else does either.  That might be a major issue at the end of the day.  The other big issue is the mounting point.  A 620 has a triangular hinge point whereas my S2R is square.  On the 620 frame, the tank hinge mounting point is raised whereas my S2R's is flat  .  SO I'd need a new bracket mount fabbed up

[Raux]

since the steel tanks have a weak hinge point, see if you can add the to tank the needed part to reach the lower hinge and add the strength it needs

[TitanMonsterS4R]

I might end up buying the 620 tank and then have the lower third of the tank chopped so a fabricator can create the rear section with the right fuel pump hole size and hinge point and then weld it back together.  Would structurally be as strong but it would get me around this hole fuel pump pressure and hinge location issue.

Nearly finished with a steel tank swap onto a 2007 S2R1000 right now.

Besides ALL of Speeddog's comments (which are right), here's my additionals:

Fuel pressure between steel and plastic tank bikes is common @ 45psi. So, you'll need to plumb in a pressure regulator from a steel tank bike to make the system hold pressure.

Steel tanks from 2000/01 M900's are NOT compatible. Do not buy unless you want to do major fab work under the tank (although they hold a bit more fuel...).  Only get 2002-early 2005 tanks. (2005 was a split production year for tanks with early being steel & late being plastic).

You'll also need the tank hinge bracket & hardware.

On this swap (also a formerly dented tank), I had the tank hinge area welded or brazed up before doing the internal coating so as to avoid future issues later.

Also, old internal fuel lines get weak and brittle.  Buy NEW submersible fuel lines to go in the tank as replacement is a PITA later.

Look for my latest custom to debut later this month or February...

[Duck-Stew]

One more thing: a 2002-early 2005 steel tank will clear the battery and air-box in their stock locations...

Filed under "Also will not fit" is the 2001-02 S4 tank (without a lot of component relocation).

Ducati went to one under tank form for 2002 on 2V bikes and kept it (2V or 4V) the same until they quit doing steel tanks.
