Hi
My first BMW was a 1978 R100 , 97,000 miles in ten years . Moved on to a R69s even had sidecar on part of the time . Then a 1980 R100 RS , 1998 RS oil head and that ended BMW riding for a few years . 165,000 miles total on the four Beemers .
This September I found a $1000 1979 R65 , little rusty crusty but mostly stock with luggage . Working my way through maintenance and some charging problems , first 1000 miles and I have made it home every trip so far!!! So here reading and learning more about the R65.
Will put a picture up of the R65 , having cord problems loading to my lap top for now .
Happy New Year !

I was not sure I had loaded that picture so I didn't make a comment about it.
1977 RD 400 --- RD350 wheels gauges

I'll make a comment about your magnificent RD... WANT!
These 350 & 400 Yamahas ruled their road racing class for more years than I can remember. Really nice street fighter look. Kenny R would ride it!
Welcome to our disorganized asylum.

Welcome to our disorganized asylum.
+1 i raced an RD350 with as many TZ bits in it as the class rules allowed. It humbled many a larger capacity bike.
If you swap your wheel and fork legs around you can reverse the disc caliper so that it is behind the forkleg. i doubt that it makes much practical difference but back in the day I could bore you endlessly that it did.

This is my R65, 79 frame , 1983 motor with points . Fairing is gone and removed Krauser top box . No telling how many miles on the motor ?
Fighting a charging issue , new voltage regulator and diode board. Motor charges at 13.6 wright up till 3,500 rpm then drops out , lower the rpm back below 3,500 goes back to charging . Bad rotor breaking down under increasing centrifugal force ?

Try the picture again.

Could be brushes. Start a thread in the tech section and you'll get figured out in no time.

I'd go with brushes too.
Although, if it still has a mechanical regulator I'd bin that on principle and replace with an electronic one - in Australia Bosch RE57 is a pin for pin replacement, the more common RE55 will also work just fine, the missing pin is only an earth and the mounting to the frame supplies that just fine.
PS. If you are interested in selling that top box let's talk
-
I sold the top box a week go .
-
Nice Reynolds rack under the box. I think I have one of them up in the attic that came on my '81 RT when I bought it...

At the time I posted this I wasn't sure of the motor I had and no one made a comment. The motor is a 1983 R80 RT that was changed over to points ignition . I and some would say the points are well why would they do that . I am happy to have points condenser ignition . Still has the 31/9 (3.44) final drive.

My wife also owns a R65/80 Frankenbike - they accelerate pretty well for an airhead don't they..... I used to pull wheelstands on her bike for fun and giggles (and also because most people wrongly believe that you can't do wheelies on a shaft drive bike, or an airhead for that matter) but SHE put an end to that about 20 years ago....
Like yours the "points in a can" system was transferred from the blown R65 engine to the R80 engine. After eating several Piranha optically triggered ignition systems I fitted a Boyer Bransden system in the early 90s, it is still working perfectly.
It took until mid last year, or 28 years of nagging, for her to get around to buying a set of crash bars that suit the bigger engine, or to put that another way, for 28 years the rocker covers protected the engine crash bars from damage due to the R80 engine being a few centimetres wider than the R65.
Oh, by the way, if you frequent some other BMW forums be prepared to be called a liar because the "small" R65 frame apparently cannot mount the bigger engine - there are some really dumb people prepared to hold their clueless views at the top of their lungs - but you may have already discovered that (BTW the front part of the frame, at least in regard to the engine and gearbox mounts are identical from the R60 through R100 and in fact I believe that you can bolt a "modern" engine and gearbox into an R69 (and older)). The short forks and the SWB swingarm and rear subframe are the points of difference for the R65, pretty much everything else is the same as its big brothers.
Look forward to interacting further with you.

So why did 'SHE' put an end to it may I ask (maybe I shouldn't) and I am right in assuming you are refering to your apparently long suffering wife? Was she more worried about damage to you or the bike?
-
I remember seeing a /2 with a R90 motor in it in the infield at Daytona in the early 80's . He told me it was a very easy install , or was that a vw engine ? I use the RD and the S3 for the occasional roll on wheel elevation.
My R65 with its R80RT is the perfect bike to have had the transplant ,
not very pretty up close , but all there an original out side of that . I dont know the history of the motor transplant but would like to know how the 650 engine met its end.

Met to add this pic, maybe this time.
