Wasn't much going on Saturday evening, so I started messing with the Paso. Here's what I ran across....

1) Fuel tank had lots of gunk in it
2) Fuel tank petcock was partially clogged with junk
3) fuel pump ground was disconnected - fuel pump works when reconnected
4) several wires were disconnected
5) Pulled vertical plug and got spark.....and then the starter relay got stuck - I had to disconnect the battery to make it stop
6) The headlight fairing was being held on by some safety wire and the dash was held on by zip-ties
7) there is no recirculation line from the outlet side of the fuel pump, back to the tank.
8 ) I pulled the timing belt covers and the belts are the newer ones with red-lettering. The bearings/pullies for the fixed and adjustable tensioner have some surface rust on them. I plan on replacing belts and both sets of bearings/pullies.

Questions:
1) The headlight fairing only appears to only be held on by the two screws that join at the upper section of the tank. The panel under the dash doesn't help hold the headlight fairing on. Parts schematics and shop manual show nothign different. Shouldn't there be some type of other support for the headlight fairing?

2) How does the dash mount to the bike? The parts manual and shop manual didn't seem to be of much help.

3) Do I need to put a recirc line back on the fuel system with these Dellortos? Right now, the fuel goes from the tank, to the fuel filter, to the fuel pump, splits off to each carb, and there is a hose that ties each carb together. There is no recirc line back to the tank, but I feel that it needs one according to the original fuel line diagram and the fact that I am still using a fuel pump.

4) Anyone know of a good way to clean the tank of rust and dirt? Should I attempt to use Kreem or Por 15? Any way to clean it really well and maybe reseal the tank without damaging the exterior paint?

If my exhaust parts come in on Wed, I'll try to put the exhuast system back on the bike and see if it will start. It is almost looking like the bike not starting is a fuel delivery issue due to a dirty tank.

Thanks to any help you guys can give me.

I can help a little on Item 6, question #1, 2. The dash mounts via rubber isolators that have threaded studs on each end. They attach to the headlight cowl frame. The headlight fairing, I remember to be a bear to attach over the frame and dash without scratching the tank near where it bolts to it. The fairing rests on and around the headlight, while also being supported by two rubber"stoppers" attached to horn like projections on the front/top part of the support frame, along with the obvious attachements to the tank and rest of the fairing as you said. You do have that headlight and dash framework under the fairing don't you? The mention of zip ties and safety wire have me wondering.
I have the frame and isolators as spare parts. Maybe I will figure out how to post pics here today and be able to show what I am talking about later.
I am not sure what to do about #3 and #4. I sure hope that when you tackle the starter issue and clean the petcock it will start. I have the Weber on mine. As a side note I had the plastic tee (it was actually a "Y") in my line too. I saw mention of it elsewhere that they get brittle and break over time. I found mine to have a carb jet shoved inside of it. I assume this was their attempt at regulating fuel pressure to the Weber.

Here's the isolators next to an earplug for size referrance.
I looked through my file but couldn't find a part number for them. Sorry, I though I had it.

Have 4 NOS "dampers" that are slightly different[rubber portion larger in diameter and hour glass shaped]. Part # 70010131a. These were for 907, don't know if these are what you need.


Edit, kinda think if diameter of the pictured dampers is smaller then maybe clearance issue with mine.

Ok, here are two more pictures showing the carb mounted on the horizontal cylinder. Remember when looking at these, it is just like you'd see them if you were standing next to the bike. I did not angle these pictures in any way....

Those carbs aren't going to work like that. They can be at a slight angle, but that's just not right. I'm guessing the manifolds are on the wrong cylinders?

They should look more like this on a V-twin...
