Thanks Gunner and Vaughan, (only replies I've seen so far) Gunner,
those sites were exactly the sort of thing I need. Had heaps of bikes
but know bugger all about BMs. I bought the bike. Rear disk. Bit
rough appearance wise but seems mechanically sound. The mechanic that
put me on to it knew the bike and told me it was good. The ex-owner
seemed like a straight shooter. Has the two panniers and top box.
Stainless exhaust. Always wanted a BMW. Paid $Aus4000, which seemed
quite reasonable after checking mags etc. I like it! All in all, a
good day. Thanks again. Some blokes, when having a mid life crisis
get the blonde and Porsche, me, I get the bike and me knee fixed! :-)
See ya, Mac.

G'day,
I'll be looking at a BMW RS100 this pm, possibly buy.
Has 94000ks (about 56500 miles). 1982. Some wear in final drive,
'clunk' when taking off from standstilll. Fairly common I think?

Anybody had/own one of these? Anything I should look for in
particular? Any traps? Have had bikes before but this will be the
first BMW. Has Brembo brakes and ss exhaust. Tia for any comments.

Regards, Mac

Ive got a R90/6, '75 model. It has 187,000 miles on it.

The clunk is pretty common for Beamers. Its the nature of the beast
and may not be final drive wear, particularly with that few miles on
it. At 56,000 unless the previous owner was a kid knee dragger
(unlikely with that particular ride), its just broke in.

Just be aware..that older Boxer rear brakes are....a bit...inadequate,
if you have the rear drum.

Put it up on the centerstand, pull the rear wheel and check the final
drive "lovejoy" couplers. The gizmo that connects the rear wheel and
the final drive. They are replaceable, but spendy if they are badly
worn, which they shouldnt be at that mileage. YMMV

Also drive shaft spline, when you have the time.

Also, check the 'gaiters" on the front forks. If they are cracked or
broken, they WILL need to be replaced. (gaiters are the accordian
rubber tubing covering the front fork sliding sections.

Oh..the boxers of that vintage have a surprising amount of kneel..when
you cram on the front brakes, they tend to lean far forwards..makes
you feel like you are about to do a summersault. But if the previous
owner put Bembo brakes on it, he may have modified the suspension.

Good bikes.
Ive not had mine on the road since 98. No time, no money. But I fire
it up every 6 months and run it till it warms up, and change the oil
once a year. Someday when Im rich and famous, Ill change out the
point style ignition and put in an electronic one. Shrug
