1986 r80g/s

I'll be looking at an R80G/S this friday. It just showed-up for sale and since they"re rare...
So the question is: What should I checked first? I currently own a 1986 Transalp.
I really don't know much about airheads! And that would be my first BMW...if I buy it!
Any advice?
Thanks,
Eric

Find an experienced airhead fan to go with you, after getting him/her to swear they won't buy it out from under you. If the price is in line with it's condition, buy it. A late R80G/S is too cool to pass up.

The only thing hard to find for these bikes are instruments and body panels.

I have bought several bikes by having an Airhead Club member in the area look at it. I also have looked for others - in one case bought the bike myself and told him if he didn't want it - I would keep it.

Oh contrare.... there are many Airheads in the Quebec area and if you join the internet club will have a wealth of support for your wrenching. Even folks from that wasteland below you will want to wander up...eh....or...we. The amazing thing about the airheads is they still make parts for them and there is a worldwide network of aftermarket stuff.

I'm back!

Bought the bike. The phone rang while we were sitting at the kitchen table. The seller answered: "Sorry, I just sold it".

The transmission is original. He took the crank off because he didn't want it to hit his leg while riding. I have it.
Rear fender will be replaced. Fork will need attention. It was reinforced but to me it looks like a "field-fix". I can easily make a better looking part. Maybe with stainless steel.
Compression: 118-120 cold. What do you think?
Back later.

The spec in the factory shop manual is:

Good: >128 psi
Normal: 107-128 psi
Poor: <107

I'd say you won.

Either Solos got some serious carbon buildup, a shaved head, hi-comp pistons or a combo of all three because 150 is off the charts. At least it's definitely holding compression though.

Just ain't no way to hit your leg on the kick starter unless it's bent. They can still last a long time that way though.

Or the teeth are broken off inside the tranny...or the lever pin was bent on the shaft. That would cause the lever to stay out too far.

It comes with a few spares... I'd ask about what work (engine internals i.e. pistons & valves) and gearbox repairs, carb rebuilds have been done. If he's kept it serviced and running I'd try to knock a bit off the price. If it is what you want then they don't really come up for sale in your area too much... so an extra few hundred dollars for something local sounds about right... as long as you are happy doing any major work yourself due to a potential lack of local airhead mechanics. If you take it and don't like it let me know and maybe we could work something out.

Well...it comes with a second set of wheels with knobby tyres. Frame and body were repainted, fork seals replaced. From what I remember. It's a Paris/Dakar edition. Fork bearing replaced too. Rear brake and air filter and new battery. 70 000km on the clock. Corbin seat...(wich I would replace with a solo seat) BMW tank bag, Original Krauser cases, crash-bars....of course it's a Paris/Dakar! Seller is asking $5000.00 (cdn) FIRM. Says both engine transmission/final-drive are in "very good condition".
I'll be there on friday...with my trailer. Since it's a 2-3 hours drive... Too bad I don't know a airhead specialist!

Thanks,

Eric

Man, sounds like a fair deal. The wheels alone could sell for a grand!!!

How many miles??? Look for the kick starter sticking out from the side cover, it should be tucked into the side cover a wee bit. I forget what gets bent or messed up when the kick sticks out, but doesn't mean the tranny is toast though.

Patched together wiring under the front fender too.

Ask about oil changes and such, the regular maintenance. If it has over 80,000 miles, you might figure a top end job is in it's future and sometimes tranny bearings fail near this time. Grab the rear and front wheels to check for excessive play. If the frame and body have been repainted I bet it's been taken care of. Probably had the tranny out for that and lubed the splines and inspected or replaced clutch.

Oh yes I have seen that ad, been posted for about 3 weeks.

"Modele tres rare, moto de collection , peinture neuve de la carosserie et du frame ( powder coating), bearing de roues, fourche et swimgarm, frein arr., filtre a air changés, batterie neuve. Le moteur ,transmission et final drive en tres bonne condition. Equipée avec selle Corbin, Tank bag de BMW, Valises Krauser,crash bars, vient avec un second set de roues. "

Too bad I am not there right now, I certainly would have gone and looked at it, I could use a bike out there, and brought my compression gauge/leak down tester.

Looks like he replaced all the bearings....good thing but I just hope the PO did not give up after looking at the price of other parts needed and decided to sell for that reason. Just what is happening with the 87 100GS I have in pieces right now, but the opposite he did the tranny and gave up on the bearings/driveshaft then lied to me.

Missing a mirror,left is non-OEM. Missing both side covers. OEM rear shock never lasted more than 15,000 kms for me...????

Looks good, price is about right but expect to spend more if you want it truly "collector".

Bonne chance!

70 000 kilometres is about 43 500 miles...

Thanks for all your answers. I'm taking notes!
