Let me start this off by saying there is a pro and con to everything. The pros to this is you don't really have to ever worry about your tank getting dented again. Also your bike is a few pounds lighter. The cons is if you use gasoline with ethanol, your tank will likely swell due to the nylon absorbing the ethanol.  Also to keep your tank from swelling, you will need to use gas with out ethanol. Having said that, you will have to remove the ethanol yourself by adding water to your fuel, shaking the can, waiting for the water/ethanol to settle at the bottom. Then remove the water/ethanol mixture as they bind together. All that is left is pure fuel. If you can deal with that, you can deal with the tank mod. So here is how I did it.

I have a 1999 M750. I bought a 2007 Monster S2R plastic fuel tank in pretty god condition.
Next I bought a 1/8" 5.5in mild steel disk. I then took masking tape placing it all around the fuel pump flange inlet.
Next I then cut a perfect circle around the entire flange area.  Once complete with that I used a pencil to shade over the screw holes to let me know exactly where to drill the holes in the steel disk.
Next I took the masking tape off the tank placing it perfectly on the steel disk.
Next I took a steel punch marking the center of all those holes.
Next I removed the masking tape and drilled out the holes.
Next I went to Home Depot and bought a brass 3/4 inch Union fitting which had all the parts I needed to complete the fuel sensor portion.
Next I took a hole saw and boared out part of the Union fitting. The rounded part you can throw away. Keep the nut as it is exactly as what you have on your metal tank. Just brass.
Next I marked a spot on the steel disk a made a small with a punch.
Next use a 1" hole saw to make a perfect circle.
Next I went to auto zone and bought a 5/16 fuel fitting.
Next I again made a mark on the steel disk with a punch.
Next I then drilled out a hole to the exact size of the fuel fitting.
Next I then took the pieces fit them together and tig welded them onto the steel disk.
Next I cut of the inside tank portion of the disk making it flat.
Next step is to powder coat the part for optimal protection. 
That's it.

You will then have three hoses that connect to your new plastic tank just as you did your steel tank. You will have a bleed line, a drain line, and a fuel delivery line. Connect them all and you are all set.

I would have posted pics but this does not show an option. I will put them up if someone can assist.  Thanks and enjoy the mod.

Refer to www.ducatimonster.org for pics.  Look for the thread in the mods section.  Thanks.

You can't pay me enough for the visual assault...the intellitext...and the lack of community...but that's just me.

BTW...I've shipped a lot of tanks and the plastic tanks are no lighter in my experience.

Me too.

There will be a weight reduction due to diminished fuel capacity

Well, i put this on here to help others that wanted to due this mod.  I wanted to do this as it was a custom project.  The only thing that makes this bike a monster still is the title as it has been converted with an MV Agusta tail and exhaust system as well as engine.  Only a monster frame, wheels, and tank.  Pictures were going to be posted but due to my LACK OF COMMUNITY, I dont care to post anymore on this subject.  As I spend 3/4 of every year overseas with the government, I dont have time to play who wants to post the most.  Good luck.  THAT IS ALL 

 Hmmmmmmmmmm. 

Fattire- he meant the lack of community at the other competing / spin off ?   site you mentioned.

Now I'm here to say we want pics or it didn't happen ! Sounds cool.  We don't go to the other side. 

I use tinypic.com.     Super convenient to use.
