G/S tanks also had a screw on filler cap, and not the recessed version as fitted to the ST.

Kev, I think that was true in the first year(s). My 86 has later flush cap and in fact had the SHED filler neck till I took a saw to it .

But I think they all had the knee indents - otherwise very similar to R65 tank.

Since the subframe from the GS is wider it required a new seat, and since I had to buy a new seat anyway, why not a badass solo seat? The subframe was pretty much bolt-on, but one of the mounting holes was about an 1/8" off and required a little tweaking to make it work. I got the idea from this thread:

http://www.advrider.com/forums/showthread.php?t=78107

Don't worry, there were no permanent modifications made anywhere and I saved all the original parts so it can all be put completely back to stock again.



This shot shows it a little better - there's a bit of a gap between the seat and tank, but overall I think it's a huge improvement.
Okay, not being of the GS nor G/S bloodline, I need to ask a question: you have a monolever bike that was crashed, now you are using a paralever subframe, correct? So there were no necessery mods to the drivetrain etc since the shock mount is to the main frame? Problem is solely with fender mount etc? Then the G/S seat fits, but with some room between the tank and seat?

I am getting more and more intrigued with the R80 and want to learn...... this is great fun.................

A couple clarifications:
First off, I didn't even crash. Just riding a dirt road was enough to bust the subframe.

Second, it's a GS (not a G/S) seat

I decided to go with a GS (not G/S) subframe because it's quite a bit sturdier, also because it allows me to use the GS solo seat that interfaces with the GS tank (also not G/S) that I added previously.

If I had stuck with the original tank and original subframe, I could've used a G/S solo seat and rack (still available new out of germany) with no gap.

To answer your question though, no. No mods to the frame or subframe or even the fender. I just bought a GS fender instead of modifying the original as I want to be able to put this thing back in stock unmolested form should I ever feel the urge. The subframe just bolted right on with a little persuasion. Three of the holes lined up perfectly, but the bottom left was off about 1/8" and took a little bending to make it line up, but nothing serious at all.

OK... thanks.... that clarification was what I was not understanding.... I thought that you were using a G/S subframe, with no mods.... Got it, now

G/S tank

[quote=Airhead Wrangler]Just to clarify: That's "original paint" from a G/S. The ST only came in two stock colors: metallic red and metallic grey.

Thanks for the clarification Airhead Wrangler.
I've had the bike about six months. The PO mentioned giving it the G/S appearance and I'd read the ST only came in metallic red or metallic gray. So the tank is early G/S, pre '84?
I'm assuming the paint is original due to the type of wear adjacent to the seat and no obvious repaint.

Great looking bike you have there. Good story too:

larger tank

rcs.ptlwtx, in my experience there are no fitment problems with the larger tank, but I can only speak from my one example.

Some have reported the GS tank aft securing loop is larger and needs to be replaced with the ST variety. Maybe a short length of fuel line could be slipped onto the loop to take up the difference, if necessary.

How do you like your cockpit fairing?

Only issue I had, and others on the Yahoo ST group, was that the GS tank creates a small gap between the front bottom edge of the seat and the tank. The top front of the seat meets with the tank perfectly though. Purely aesthetic. I didn't give a shit. E-Kev, it looks like we have another red ST with black stripes coming soon.

Change the securing loop for the ST one, and you will need to buy some more fuel line, and a T piece, as the GS tank has two fuel taps, the ST only having one.

I don't care about the small gap either, in fact it saves the seat rubbing on the tank! The GS tank is the best upgrade you can make to the ST in my opinion, it changes the whole look of the bike.

motorbike came with National barn door-post 37, took it off, rode naked (the bike) for a year. "winter" fairing -post 38 found on e bay. in spring swapped to cockpit fairing. best configuration possible for me, I'm 5'10", surprisingly effective (did they do wind tunnel work), don't know its there, nice pocket of still air, we'll see if its enough in January though.

still have the National fairing, almost new, all fittings, available for cost of shipping, free for Houston pick it up. deliverable to Dallas or Austin.

I saw an ad on IBMWR this afternoon for what sounded like a gorgeous R80ST with several thousand original miles, silver in color, asking $4,200.... I was thinking, man, if only....but my reality is grim right now. Sooo......

Thought I should post it up here: went back just now to cut and paste the info, and it has been taken down....






SOMEBODY just got themselves a beauty, I do believe..... any 'fessing up out there.....??
