'85 r80 g/s

I am picking up a new to me 1985 R 80 G/S Paris Dakar tomorrow.Pretty much original.
I have only seen it parked between other bikes.Did not hear it run yet.
Bought on sellers word, who I trust.
93,300 kms.( 58,000 miles)
Owner says it WAS a Gaston signed tank, but it wore off.
Any way of confirming this by the SN ?
Thanks guys.

Yeah,I know: Pics in a couple of days.

I don't think you can determine if the signature was present using the Serial Number. The tank was a dealer option add. Without the invoice I would look carefully at the tank, if its still white, to see if the shadow of the signature is there. Otherwise enjoy it. The PD tank is great and if in good shape it is rare.

Ok, got it in the shop.
Looks good (pics in 2 days)
Wiping it down and checking it over.What am I looking for? Tank and liner is dry,pristine.Bowls were drained.
No major oils drips,some oil and dirt around the push rod tubes.
Battery was taken out a long time ago.
Charging battery now to see if it is recoverable.
I grabbed a spare car battery to check the electrics.When I hook up the + and touch it to the heavy starter wire (key off)
I get major sparking.Hooking up to the other 2 + wires, all lights and all dash lights appear functional.
The signals do not flash, that is no biggie.
It does act like there is a major short in the starter area.
Will get the tank and starter cover off tomorrow and do some tracing.
Hesitate to think that the PO knew about this, but who knows?
Anything else I should be looking at?
Thanks.

Got a digital multi-meter (DMM)? If not, go buy one. Doesn't have to be an expensive or fancy one either. I just bought a decent, rugged one for $25.

With the battery out/disconnected and with he switch ignition off, there should be no current draw on the battery. A measurement between the positive battery cable and the engine should read infinite Ohms. If is is near 0 Ohms, you have a big time short. But just start following the cable away from the battery and disconnecting everything as you go. You will find the short.
Do you hear the starter try to spin when you connect the battery? Maybe just the starter relay is welded closed.

Thanks Moto,I have an inexpensive analog tester.My expensive digitals are all broke.
I was thinking of the testing as you suggested.
Electrics are not my strong point, infrequent use is my reason.
The starter does not turn, or try to.Just a big spark when I touch the main wire to the battery cable.
Tear down tomorrow.

I cannot open the link Left T.

Problem solved !

Dug around a bit last night and this morning,finally called the PO,he was concerned that the bike was giving me trouble.
Then he asked me if the heated grips were on.They were after market and bypassed the ignition switch.Direct hookup to the battery.I had pondered on that switch on the handlebar, but did not follow it up.He said they were quite effective,big current draw, therefore the light show when I touched the lead.
It was on, all is well.
Not running yet, but the engine does turn over.
Thanks for the support and help.

Pics tomorrow.

Drop the oil pan, and clean it, plus inspect the oil pickup tube, remove and clean. It's easy to do, and would get rid of any sludge which might have settled since the bike is low miles and if oil has sat in there to long in a questionable environment.

Nice shop! I have to work in my low overhead basement if I want to work indoors.
Oh, nice bike too.
