I have a 2002 M750, will a 2002 Monster S4 tank fit my bike?

If I recall correctly the S4 tank has a considerbly lower fuel capacity . . . you might want to reconsider.

Go here (http://www.ducati.com/en/bikes/service/parts/2009.jhtml?family=parts).

Check the parts manual for your bike and the S4, if the part number is the same then it will fit.  My current tank is off of an S4, it was the same part number, and I had no problem with it.  Same fuel capacity too. ;)

Thanks Krolik, its the same part number so it will fit...... [thumbsup]

Now about what chuck says....is this true?? Chuck you sure about that?  I would think if its the identical part number, then it would have to be the same tank, so the fuel capacity would be the same no?

I got a chance to buy a red 2002 S4 tank for about $100. Id have to swap all the parts off my current tank over, like the fuel cap, hinge, fuel injected internals ect but the tank is in good condition, no scratches or dents.  I guess id have to say goodbye to the black color bike but ive always liked the red ones too.

Same part is same part.... DO IT!!

I defer to Krolik and Ducati PNs matching.  It may have been a different model year I had read about.

I'd do it, and if the color is going to bother you, paint it now since it's off the bike already...  I hear yellow is the 'in' color this spring... :P

Good luck and nice find!

Go by P/N, obviously.

I think Chuckles was thinkin' of the later S4Rs tanks... I'm pretty sure the bikes with the Testastretta engine have a different airbox (which sticks up in the middle of the fuel tank), and they may be the bikes with smaller tanks.  Not sure about the 996-engined S4R.

JohnnyD, or anyone else with an -Rs care to chime in?

You guys if the PN is the same, shouldnt the gas cap/fuel injection stuff/hinge ect. fit as well?

So this tank for sale is off a 2002 S4 (he says its off a 1000 so im figuring that means a 996) i checked its the same part # as my tank but the tank comes without any hardware. I just want to make sure all this stuff on my current tank will be able to be transferable. I dont see why not, as long as its the same part #.

Check the parts manuals again for the hardware part numbers.

Every part is the same, fuel system parts are the same, tank part numbers are the same, every dam screw part # is the same between the two bikes EXCEPT for one part. The Tank cap. Part number is 895.4.004.1A for the S4 and 895.4.001.2A for the monster......hmmmm..... shoot ill just have to chance it. Maybe it was just a different rev. of the same thing.

The S4 cap probably just has a logo or some other cosmetic difference to match S4 trim. If all else is the same, there will be no problems. Throw on your cap and call it good.

Worst case scenario is you'll have to go down to MotoCorsa or look around the web and buy an aftermarket cap.  Sounds like everything else is gravy... go for it.  [thumbsup]

(FYI, if the tank P/N is the same, then the mouth that the filler cap mounts to would have to be identical, regardless of what the filler cap itself looked like)

Well the tank i was going to get got sold....so im going to weld mine. I spent today just trying to empty the tank and get it off the bike. Those hoses were on there good. Got the tank off, but man its hard trying to empty out the last bit of gas, even with the tank off holding it upside down and shaking it with the filler cap off you can still hear a little bit of gas in there.... Anyone ever taken the low fuel sensor out before? theres a wire that goes up in there that plugs into the inside of the front of the tank? How are you suppose to unhook that and hook it back up?

I don't think I gutted mine, the brazing (not welding) keeps the heat pretty localized.

The brazer will likely flood it with inert gas during the actual operation, but I think I rinsed mine out with hot water before taking it in.

Well it will all come together in the end i suppose. I got more answers off this board about the fuel sensor and how to take it out. If this actually works out, the tank doesnt explode from welding, were able to get the tank smoothed out for a good paint job (the surface is pretty rough, someone popped a dent out and left the tank cracked, badly bondoed and pits and little chunks taken out of the tank) Im thinking about painting it matte black instead of gloss black, then putting a dark red ducati logo on it. Man even being carefull i wound up getting gas everywhere, on my bike, and on me trying to drain the tank out and get the tank off. This is only step one of this process. I think my bikes gonna be down for a month or so til i get this done and back together.  [drink] [laugh]

Stop saying welding, you want it brazed.  Welding won't work very well, and you want to ask for the right thing when you get it done.

my father in law is doing the welding (brazing) im just along for the ride.  He used to weld MC gas tanks hed go racing and crash and crack them all the time. So i dont have to really worry what i tell him other than, ahh its leaking gas out right here....and point.  [laugh] Ducpainter told me brazing is what you do to the hinge when it cracks. Hell i dont know the difference. What is the difference?

Welding melts and fuses the base metal, and brazing ("braze welding" when done with a torch and rod) essentially glues and fills without melting anything. It doesn't cause stress and won't distort the base metal.

So instead of burning and potentially widening the crack you're trying to kill, on top of changing the dimensions and properties of the tank thanks to heat, you're filling it without disturbing the delicate-ass tank walls. It also looks prettier when done and isn't as hard on paint.

wait -

is yours not leaking at the hinge?

mine is leaking at the hinge haha.

a word of advice to everyone.  When you have to take the tank off.  Use a gasoline hand cranking pump to get the fuel out.  Use a piece of wire to help guide the tube into the bottom of the tank(figure out how to mount the wire to the tube yourself).  I got about 98% of the fuel out of my tank just last weekend when I did this.

Just need to call Macs Radiator and schedule a time to head up there with the tank.


Good luck

No thats jducati, my actual tank is leaking someone dumped it then pulled out the dent where the handlebars hit and put a crack in the tank on the side of the tank itself.

Hey i just took my tank off today, went and got one of those tubes from harbor frieght with the bulb in the middle. Did a good job getting most of the gas out, but these tanks have some hiding places for gas.  It all went fairly well in the end. I got the tank off, and in the end no matter what i do i cant get that little bit of gas left out of there. I hear it in there when i turn the tank upside down and rock it back and forth. I need to get all of that out, did you have any problems getting every last drop out of your tank? Did you take out all the inerds?

There is still some fuel left in the tank.  I will be taking the pump and filter out of the inside of the tank so it will make their job that much easier.

I know that Macs Radiator has the tools required to get rid of all the fuel inside the tank.  I did ask them about that when I talked to them.

I think they call it a match!

Take rags

put in tank

lay tank upside down for a day

take rags out

No gas in tank

I took the tank off my SV with it full of gas.... no leaky.... he he he.... but it is really farking heavy that way.  [bang]

Leaking at the tank is common, and an easy fix.

I hope your FIL is good.  That's going to be a tough fix, and really hard to make it look pristine again.  I guess you will need it welded though, brazing probably won't work if the sheet metal cracked in a crash.  I'd probably be shopping for a tank if I were in your shoes. 
Good luck.   [thumbsup]

I figured id see how it goes since its free (welding) and use it as a project. If in the end, it looks like crap and i cant seem to get it good even with bondo then ill skip the paintjob and just buy one off ebay. No matter what, i have to pull my tank off my bike, and pull all the hardware and innerds out of my tank to swap it to a new tank. So i havent really lost anything.  At least this way im giving it the old college try, and learn something in the end of all this like whats inside the tank, how to take my tank off and take all that crap out and put it back in. Whatever, im old and have nothing better to do.

You might try putting a lit match to the tank while the remaining fuel/fumes are present, this may result in dent removal  ;)

Just my 2 cents boss!

I never thought of that...... [thumbsup]

We used to put fire crackers in bent beer cans.  Fixes 'em right up.

Eyebrow removal too. :o
