TiiMuch, the gauge is a Motogadget Motoscope pro. As far as the tank goes it required some fabrication to fit. If you look on all of this era frames you will notice the earlier frames have the studs mounted farther ahead behind the steering head. The later frames like mine had a separate mounted welded farther back and underneath the top frame brace. I cut this mount off but there are still holes on the head brace where they welded the studs in. I just welded in new studs in these holes. The rear mount is also different but the rear tank pad is very close to the same and still works. I just fabricated a new bracket that the bolt assembly screws in to.
A little more fabrication... I decided to find another tank and install a new style filler from an SRAD GSXR.
The donor tank. Beat up but clean inside and the filler is in nice usable condition.
The cap is a UK built Oberon.
I marked out the hole and 7 1/8" looked like the magic number to get the filler and tank to match up nice. Plus that's the size of a sanding disc I had and the closest thing that would let me mark a round hole that was big enough. Damn that looks like a big hole!
Sizing up the vent and drain lines.
Cut and fit in place. I drilled a pilot hole and used a fine bi-metal blade in my jig saw which ended up working out very well. It looks pretty good here other than the edges of the filler that need to be tweaked down a little to match the tank.
Here you can see how I straightened the lines and bent them down for the new outlets.
Then I carefully measured and marked the holes. I drilled them to the inside diameter of the lines. Then I heated up the area around the holes and gave them a few good taps with a tapered punch to open them up to the outer diameter of the lines. This will give me a good filet for the brazing. Welding will make the lines brittle where they will eventually crack. Don't ask me how I know as I speak from experience building a gas tank for my Bronco. This is why they braze the lines from the factory.
A little tweaking by hand rolling it along the top of the bench it she fits pretty nice.
Now to trim the tank and filler to fit and weld it all up. And finish braze the vent and filler lines once that is done. Grind and smooth it all out and hopefully I won't have any issues with it warping too badly. Then I'm going to paint it black with factory stripes like my other tank.
