Gloating in the frozen north...

[Roguetek]

HA! suckers... I aquired a -running- 1976 R75/7 and basket case 78 R100/7 for ...

1 thousand dollars american... BWAHAHAAHAHAHAHAHAHAAHAHAAHAA..

:dance :newtoy :newtoy


the R75/7 is pretty much bone stock, and all the bits are there. it's got one lil ding in tank, and a bit of storage funk.

the R100/7 has had things -done to it-.. dualfire heads, modified ignition, and some sort of flywheel mod. PO says something about a 'racing flywheel.'

all of the factory fairing parts are there for both bikes. no bags, but hey, for a -grand-?


neener neener neeeeeener!

I"m gonna keep the R75 stock, and do horrible -horrible- non-stock things to the R100... I"m looking at the way the exhaust passes by the carbs and thinking 'turbocharger'... any one ever try this?

[rinty]

Welcome.

The "racing flywheel" is probably one that has been lightened by one of the airhead modifiers, such as San Jose, or Luftmeister. The pre-80 flywheels were heavier than the later ones. It used to be a popular mod.

Luftmeister also made a turbo charger kit for the litre bikes at one time, and there may be some of these still kicking around. As far as I know, Luftmeister is (mercifully) out of business. I know one guy who installed one, but the heads weren't up to the additional power.

The R 100 might be a good candidate for a nice cafe racer conversion. Check around in the airhead section here, and in the Airheads site.

Have fun with your new machines, and maybe put up some pics.

[sumran]

Was that price per bike or for both? I'm happy you got such a great deal. If you keep us posted on the work, I won't even mind that you were guilty of taunting.:stick

[ccolwell]

Nice, but /7? My '76 R75 was a /6 and I thought /7's were R80's.

[bikerfish1100]

you're right, but the /# factor really is not so much an engine designation as it is a production/sale date designation. /5 (intro of R75 motor )was '70-'73. /6 (which introduced the R90 motor) was '74 - '76, and /7 (R100 and eventually R80 replacing the R75) was '77-80 or '81; at which time tehy dropped the /7 badging, but it really was still just minor updating of the /7 line from then on to the end of production. all years are USA sales- they would typiclly show up as EU models one year earlier.

"factory fairing parts"? For the R100? That changes it from a /7 to an S ... or an RS. What color is it? If it happens to be white with two blue and one red colored stripes on it, you've got a rare bird there (one of 200 NA-spec or 150 Euro-spec 'Motorsport' versions) that would be better served 'restified' than modified.

[kstoo]

Yes, there were R75/7 's sold in 1977 ... just before the R80/7

[Roguetek]

Oh, there will be pics. I'm in the middle of moving, ATM, so no work -yet-.

according to the Vin decoder

the R75 is
------------------------------------------
Vehicle code 0312
Series K56
Model R75/7
Body type OTHER
Catalog model USA
Production date 1976 / 10
------------------------------------------

And has not been tweaked in any way. bone stock.

The R100RS is

------------------------------------------
Chassis number 6180243
Vehicle code 0316
Series K57
Model R100RS
Body type OTHER
Catalog model USA
Production date 1976 / 11
------------------------------------------

and has been.... 'fiddled with'

if I go with turbo, it wont be a lufty kit, I'll go with something homebrew, with probably about 60% of the boost of the lufty kit. In short, I'm going to keep the boost within the limits of the heads.


and yes, I -did- pay a grand for -both- bikes, -total-... Neener neener neener.

[bikerfish1100]

yes, but he said he has a 1976 R75/7. That's not a US model.

with production dates of 1976, those would likely be 1977 models in the US (my 2001 R1100S has a born on date of 06/00, for example. but it's still a 2001 model year release.)
fwiw- talking about your 1976 /7 or your 1976 R100RS will only confuse folks in the USofA.
do you currently have the RS fairing? if not- it will be quite pricey to acquire one (more than you've already paid for the bikes), though not a wholly unreasonable task.

[Roguetek]

Yup... both fairings are complete, and intact.

and both are black...

according to the VIN, the R100 is a R100RS

[sumran]

The early RS might be the better choice to keep stock, even if you have to do some unfiddling. Especially since you have the fairing. Your choice, of course. Based on your info it is an early '77 model which is very desirable.

If you are going to do "horrible non-stock things" it won't matter much what engine size you start with. And you will have the advantage of a final drive with a gear that is more performance oriented. The R100 will have probably have a 32/11 FD. Great for highway cruising, not so much for cafe use.

[Roguetek]

Hmm.

well once I get my paws on all of the bits and get them in a pile, I'll know more.

If the R100RS is a desireable model, and I have all the 'spendy bits' I might do a light resto and sell it, and buy something less rare to bugger with.

It would seem that both are... rare-ish models.So I'm not sure what to do next. I know I"m keeping the R75 stock... not so sure with the R100RS. It's already been heavily modded so it might cost more than it's worth to return it to factory status.

[rinty]

Roguetek:

As mentioned above, the '77 RS is collectible, so you won't want to restore it to anything but original, unless you are prepared to lose value. And there are lots of plain vanilla R 100's out there to modify.

[bikerfish1100]

rintydude- it's already lost value.
"desireable and collectible".... yeah, well, only if in stock condition. dual-plugged heads & non-stock paint job & some other things = not "collectible" as a '1977 first year model. it's already been devalued as a collector's bike- and nothing you do will ever bring it back to "stock, original first year R100RS" model, so I wouldn't even begin to think in that direction. even going back to original color paint will still not give you an "original paint" bike- it's "restored", at best. that would put it in contention with other restored bikes that have been fully repainted- and it will never be an awards contender.
(and sorry for what some will say is "inappropriate" or "not-pc" here, but i can't give a better analogy).... it's kinda like losing your virginity- no matter how you gussy things up, once it's gone, it's gone.
however, a RS is the ideal sport-touring airhead... so think of putting it together for that purpose. you will not find a better fairing for operational purposes+aesthetic good looks for any airhead, period. get it running right, and enjoy the hell out of it!!

[Roguetek]

Yeah...

I thinK I'm gonna focus on getting them clean, running and roadworthy... -then- I make decisions.

[R80RTJohnny]

The purchase price of the bikes will be nothing compared to what it will cost in making them "valuable" machines. Sorry but the collectable world has not quite taken to 70's era BMWs. Exception being the R90S as it has a racing history. The R80G/S series comes next. BMW even ended it's airhead run with an R80GS Basic.

At the end of the day you probably paid the right price for these bikes.

Enjoy them both. Gloating is so very gauche.

you're right in many regards, not so on some others. correct- the R90S is THE hot deal from that decade. but have you seen the prices on toaster tank /5s lately? that's the other big '70's era collectible model.
and no, the price was better than "right", it was very good, no question about it.
but you're right, for most of the others, not so much collectible. (excluding the hot deal Eurospec'd '77 and '78 RS editions, those can still pull a pretty penny.)

[Roguetek]

gauchery be damned.

I got a helluva deal, and I'm going to be disgusting about it.

as far as collector value vs. riding... well, we shall see what we have when the dust settles.

Is that my cue to gloat? :scratch Not just a '78 Euro spec, but 'Motorsported' as well ...

I gotta agree with bikerfish1100. The RS has been 'messed with' a bit too much to get it back to "Original '77 R100RS" condition without spending a buttload of money. A turbo would be interesting. :thumb

Yup! Nice pair!

Nice pair indeedy.

Are your valve covers upside down on the Motorsport? Looks like its running uphill. Seems like an optical illusion, but they are handed, like the pics in this post clearly show: http://www.bmwmoa.org/forum/showthread.php?t=28085

Might just be the angle of your pic...or my eyesight. :dunno

Anything is possible on this mutt. But the current bottoms are all scraped up so, for now, this is the way it will be ... :dunno
