Very interesting indeed !!
I have been asked to post about this, I'm more of a 'do-er' than instructor but hope this helps a bit for anyone contemplating this VERY worthwhile mod.
T120 tank is slightly tight at front around headstock, could 'possibly' be cured by rearranging wiring, a portapower & a bit of peening should sort it out, but because it was always my intention to spray whole bike I opted to do a small cut with grinder on the outside of the welded seam each side (will take a pic & add later) front of tank tunnel was then dressed outward & cuts welded back up.
Rear mounting on T120 tank cut off completely, something I have yet to do is add a metal plate from under the back of the tank to secure down with front seat bolt.
I used modified bobber rear mounting bolted in original position to locate in tunnel of T120 tank, again will have to go to garage lift tank & take a couple of pics to add.
The circular rubbers that go into the side mounting in tunnel, I cut the rear of them down to allow the new tank to sit slightly further forward, maybe 10mm.
All bobber internal stuff fits straight in to tank no problem, sender arm bent downward some to help more accurate empty reading, full does not matter, even in the bobber the sender registers full from 3/4 upward because of tank shape & limited arm movement, the lower end of the scale is far more important than the full tank end.
When I fill up now it tells me 90 miles to empty, it stays there till I have done maybe 70 miles then reads normally as more is used, when it reads empty I have around 15 miles left.
I could mess with it some more but it's fine for me I always know how far I can push it between fill ups.
So not a simple bolt on job but pretty easy for anyone a bit practical.
Thanks for that I am having trouble posting pictures with these photobucket changes,will have to move pics to a better site.

Maybe a Speedmaster tank would be a better option. According to this thread its plug and play. Picking one up wont be cheap though I fear.Hi all, I've just joined the forums & for my 50th birthday bought a Bobber Black her in Australia. I'm not very good with my hands, is the above modification difficult for someone who does know motorcycles to do?
What sort of specialist should I take a tank to? Clearly not my local Trumpy dealer...great idea with the T120 tank. Australia is a big country and 9.1L is too small to be functional here. I think the T120 tank is 14L?! Thanks in advance.
It strikes me there is potentially a decent opportunity here given the Bobber seems to have been such a success?!
Best Regards to all

trirocket can you post a pic of your bike? The original photo bucket photos don't show anymore, curious as to what it loos like.
Would the Speedmaster tank allow for proper fuel gauge readings?Maybe a Speedmaster tank would be a better option. According to this thread its plug and play. Picking one up wont be cheap though I fear.
